Принесли большое задание примерно 200 000 листов формата А4 с двух сторон.
После прогона аппарат закапризничал. Появилась серая продольная полоса примерно 2 см в ширину и серый фон с обратной стороны листа.
Чистка вала из сервисного меню помогала лишь на несколько десятков листов. Решил почистить блок проявки в ручную.
При разборе высыпалось содержимое. С дуру выбросил. После чистки стал выдавать ошибку 7101. Засыпал в приемную дыхалку новый девелопер бутылочку 75 гр. и тонера примерно пол стакана. При этом проворачивал вал по указанной стрелке.
После этого изображение появилось, но постоянно после 2-х листов выскакивает ошибка 7101, бумага остается в тракте.
Серость с обратной стороны не исчезла.
Предполагаю по первой неисправности недостаточно девелопера или тонера. Сколько примерно нужно того и другого, чтобы восстановить работу? Какую сервисную процедуру выполнить?
По второй неисправности (грязь на обороте) видимо надо вычистить какой-то бункер на боковой крышке от мусора, чтоб не налипал на ленту?
Как это сделать? Сам понять не могу.

    Taskalfa 5500i Error Code C7101

    Dear Techs,

    I purchased Taskalfa 5500i with good print quality and the machine was running fine till 5000 copies but after that print got diminished. I used 132 to add toner but nothing happened. The toner box was full but machine showed it running out of toner. I changed it with original cartridge then toner fed into machine. But this error came up and now its going anywhere. I can only make 5 copy at a time, more than that error c7101 come to screen.

    Please guide me how to set good values manually with U131.
    Screen shots are as under:

    Make sure that the developer unit is properly locked in place. If it doesn’t help, you will need to replace it.

    The resolution of your photos is too low for me to view anything useful. =^..^=

    If you’d like a serious answer to your request:
    1) demonstrate that you’ve read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you’re going to ask about jams include the jam code.
    4) if you’re going to ask about an error code include the error code.
    5) You are the person onsite. Only you can make observations.

    Thanks for your reply. I am using OEM Toner Box but toner is from other cartridge. Means i have put it from top through a hole!

    Please tell me if this machine can detect empty toner and can not used again again?

    And do I have to purchase a new OEM Toner?

    Will this help?

    5500i toners have an rfid chip that the machine tracks, simply adding more toner to a cartridge that the machine has already determined is empty will not allow the unit to add toner to the developer. Just put in a new toner cartridge for the 5500i! You said that you added toner from another cartridge, what cartridge? Is it compatible with the 5500i? All Toner is not the same. You are creating more problems for yourself than is necessary.

    Re: Taskalfa 5500i Error Code C7101

    Hello

    I have several of these machines: Kyocera 5500i Utax CD1455 and error C7101 — black developer error. I searched and dug and found what causes this rather common mistake. Although the developer has a lifetime of up to 600,000 prints, sometimes even after about 100,000 shows this error and replace it? after all, the developer is 600,000, so I was looking and it turns out and this probably applies to all development teams in kyocers / Utaxach. A film is glued between the td sensor and the developer housing, which should not be there in the developer. The td sensor housing adheres to this film and the flag itself is wiped from the other side with a flag, which after some time causes deformation of this film, so that the sensor does not overlap the sensor and the toner level sensor does not read. You should remove this film (cut out) then secure the sensor so that the developer does not spill on the bottom of the developer. In this way I saved 4 developer teams. The level of sensor reading from 15 jumped immediately on 520 and the machines have been running for over 3 weeks. I will add that you can buy the developer itself and the black magnetic roller in china

    Please guide me how to set good values m
    This error means something went wrong with values of (Developer/Toner)
    the main culprit is the t/c sensor or the ID sensor on the Developer unit
    other time (real percent is not equal i.e if toner is more than developer copies will be paled if developer is more a black background will appear while text is not dark enough
    the solution
    u should have the unit refilled with a new developer and go to U131 and execute and hit start
    (make sure you have the right toner for you machine with good quality)

    or you will have to change the Developer unit
    ——————

    Few occasions the hopper is blocking toner path so you have to make sure it’s not clogged either

    First thing I’d do is run a bunch of skyshott to get all the unknown toner out of the DV unit and then put OEM toner in and run calibration. You may end up having to replace the DV unit.

If the T/C control is not capable at the DLP or there is a possibility that DLP is LOCKing by jam in the developing powder outlet etc.

(It may be accompanied by the unusual rattling sound like no engagement of gears and C7101)

1.In case of abnormal sound occurs

a. Replace the DLP UNIT .

b. Re-assemble it as referring to below attention 1.

2. In case of no abnormal sound (developing drive possible)

a. Check the firmware Ver.and version up with most updated one and

replace

the DLP UNIT.

b. Re-assemble it as referring to below attention 1.

3. In case of no abnormal sound and firmware version is most updated one

a. Remove the INNER UNIT.

b. Check the CASS SHUTTER of the DLP UNIT.

c. If the parts is broken, replace the DLP UNIT.(Fig.1)

d. Re-assemble it as referring to below attention 1.

4. In case of not applicable above 1,2.3

a. It is possible of error at the DLP motor. Check the DLP motor.

The measure against below condition was taken after 2011 Oct. production. Therefore,

below action is not necessary if the production month is Oct. and after.

Break (bend)

When pushing in the CASS LOCK release LEVER at the INNER UNIT, there is a

case not to push in smoothly.

In that case, without pushing in by force, re-install the INNER UNIT while shifting it

by right-hand side and fix.

If it pushes into INNER UNIT forcefully, the lock release cannot be done normally,

C2101, C7101, and unusual sound occur again and DLP UNIT may damage.

attention 1

The measure against below condition was taken after 2011 Oct. production. Therefore,

below action is not necessary if the production month is Oct. and after.

Break (bend)

When pushing in the CASS LOCK release LEVER at the INNER UNIT, there is a

case not to push in smoothly.

In that case, without pushing in by force, re-install the INNER UNIT while shifting it

by right-hand side and fix.

If it pushes into INNER UNIT forcefully, the lock release cannot be done normally,

C2101, C7101, and unusual sound occur again and DLP UNIT may damage.

Принесли большое задание примерно 200 000 листов формата А4 с двух сторон.
После прогона аппарат закапризничал. Появилась серая продольная полоса примерно 2 см в ширину и серый фон с обратной стороны листа.
Чистка вала из сервисного меню помогала лишь на несколько десятков листов. Решил почистить блок проявки в ручную.
При разборе высыпалось содержимое. С дуру выбросил. После чистки стал выдавать ошибку 7101. Засыпал в приемную дыхалку новый девелопер бутылочку 75 гр. и тонера примерно пол стакана. При этом проворачивал вал по указанной стрелке.
После этого изображение появилось, но постоянно после 2-х листов выскакивает ошибка 7101, бумага остается в тракте.
Серость с обратной стороны не исчезла.
Предполагаю по первой неисправности недостаточно девелопера или тонера. Сколько примерно нужно того и другого, чтобы восстановить работу? Какую сервисную процедуру выполнить?
По второй неисправности (грязь на обороте) видимо надо вычистить какой-то бункер на боковой крышке от мусора, чтоб не налипал на ленту?
Как это сделать? Сам понять не могу.

Сильно не пинайте, я не профессиональный ремонтник. Работаю инженером по обслуживанию компьютеров, но начальство навалило еще и обслуживание копира.

Копиру год. Заправляли фирменным тонером в картриджах ТК 6305. Наработка на сегодняшний день 350 000 копий А4.

    Taskalfa 5500i Error Code C7101

    Dear Techs,

    I purchased Taskalfa 5500i with good print quality and the machine was running fine till 5000 copies but after that print got diminished. I used 132 to add toner but nothing happened. The toner box was full but machine showed it running out of toner. I changed it with original cartridge then toner fed into machine. But this error came up and now its going anywhere. I can only make 5 copy at a time, more than that error c7101 come to screen.

    Please guide me how to set good values manually with U131.
    Screen shots are as under:

    Make sure that the developer unit is properly locked in place. If it doesn’t help, you will need to replace it.

    The resolution of your photos is too low for me to view anything useful. =^..^=

    If you’d like a serious answer to your request:
    1) demonstrate that you’ve read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you’re going to ask about jams include the jam code.
    4) if you’re going to ask about an error code include the error code.
    5) You are the person onsite. Only you can make observations.

    Please tell me if this machine can detect empty toner and can not used again again?

    And do I have to purchase a new OEM Toner?

    Will this help?

    5500i toners have an rfid chip that the machine tracks, simply adding more toner to a cartridge that the machine has already determined is empty will not allow the unit to add toner to the developer. Just put in a new toner cartridge for the 5500i! You said that you added toner from another cartridge, what cartridge? Is it compatible with the 5500i? All Toner is not the same. You are creating more problems for yourself than is necessary.

    Re: Taskalfa 5500i Error Code C7101

    Hello

    I have several of these machines: Kyocera 5500i Utax CD1455 and error C7101 — black developer error. I searched and dug and found what causes this rather common mistake. Although the developer has a lifetime of up to 600,000 prints, sometimes even after about 100,000 shows this error and replace it? after all, the developer is 600,000, so I was looking and it turns out and this probably applies to all development teams in kyocers / Utaxach. A film is glued between the td sensor and the developer housing, which should not be there in the developer. The td sensor housing adheres to this film and the flag itself is wiped from the other side with a flag, which after some time causes deformation of this film, so that the sensor does not overlap the sensor and the toner level sensor does not read. You should remove this film (cut out) then secure the sensor so that the developer does not spill on the bottom of the developer. In this way I saved 4 developer teams. The level of sensor reading from 15 jumped immediately on 520 and the machines have been running for over 3 weeks. I will add that you can buy the developer itself and the black magnetic roller in china

    Please guide me how to set good values m
    This error means something went wrong with values of (Developer/Toner)
    the main culprit is the t/c sensor or the ID sensor on the Developer unit
    other time (real percent is not equal i.e if toner is more than developer copies will be paled if developer is more a black background will appear while text is not dark enough
    the solution
    u should have the unit refilled with a new developer and go to U131 and execute and hit start
    (make sure you have the right toner for you machine with good quality)

    or you will have to change the Developer unit
    ——————

    Few occasions the hopper is blocking toner path so you have to make sure it’s not clogged either

    First thing I’d do is run a bunch of skyshott to get all the unknown toner out of the DV unit and then put OEM toner in and run calibration. You may end up having to replace the DV unit.

The measure against below condition was taken after 2011 Oct. production. Therefore,

below action is not necessary if the production month is Oct. and after.

Break (bend)

When pushing in the CASS LOCK release LEVER at the INNER UNIT, there is a

case not to push in smoothly.

In that case, without pushing in by force, re-install the INNER UNIT while shifting it

by right-hand side and fix.

If it pushes into INNER UNIT forcefully, the lock release cannot be done normally,

Принесли большое задание примерно 200 000 листов формата А4 с двух сторон.
После прогона аппарат закапризничал. Появилась серая продольная полоса примерно 2 см в ширину и серый фон с обратной стороны листа.
Чистка вала из сервисного меню помогала лишь на несколько десятков листов. Решил почистить блок проявки в ручную.
При разборе высыпалось содержимое. С дуру выбросил. После чистки стал выдавать ошибку 7101. Засыпал в приемную дыхалку новый девелопер бутылочку 75 гр. и тонера примерно пол стакана. При этом проворачивал вал по указанной стрелке.
После этого изображение появилось, но постоянно после 2-х листов выскакивает ошибка 7101, бумага остается в тракте.
Серость с обратной стороны не исчезла.
Предполагаю по первой неисправности недостаточно девелопера или тонера. Сколько примерно нужно того и другого, чтобы восстановить работу? Какую сервисную процедуру выполнить?
По второй неисправности (грязь на обороте) видимо надо вычистить какой-то бункер на боковой крышке от мусора, чтоб не налипал на ленту?
Как это сделать? Сам понять не могу.

Сильно не пинайте, я не профессиональный ремонтник. Работаю инженером по обслуживанию компьютеров, но начальство навалило еще и обслуживание копира.

Копиру год. Заправляли фирменным тонером в картриджах ТК 6305. Наработка на сегодняшний день 350 000 копий А4.

This article is about how to fix error C7101 on your Kyocera TaskAlfa 250ci, 300ci, 400ci, 500ci, and 552ci copier machine. We are sharing a few methods to fix the error c4012 on the Kyocera TaskAlfa color series copier, so check them one by one until it gets solved.

Meaning of C7101 error Code:

Kyocera taskalfa 300Ci error code C7101 indicates the associated black developing unit. The black developer would be bad at the time. If the over-toner is too high in the developer unit, it cannot rotate the developer motors. This message cannot be cleared until you have repaired or replaced the black developer unit. The error code will vary depending on the toner sensor of the developing unit

  •  C7101 = Black (K) toner sensor.
  •  C7102 = Cyan (C) toner sensor.
  • C7103 = Magenta (M) toner sensor.
  • C7104 = Yellow (Y) toner sensor.

Fix C7101 error code:

  1. The black tone in the developer will be worse now. You need to remove the old toner and install the genuine toner.
  2. Replace the black developer unit.
  3. Check the developer’s motor.
  4. Replace the engine PCB.

I hope this was helpful, don’t forget to share it via any of the share buttons on this page are highly welcomed as well.

    Taskalfa 5500i Error Code C7101

    Dear Techs,

    I purchased Taskalfa 5500i with good print quality and the machine was running fine till 5000 copies but after that print got diminished. I used 132 to add toner but nothing happened. The toner box was full but machine showed it running out of toner. I changed it with original cartridge then toner fed into machine. But this error came up and now its going anywhere. I can only make 5 copy at a time, more than that error c7101 come to screen.

    Please guide me how to set good values manually with U131.
    Screen shots are as under:

    Make sure that the developer unit is properly locked in place. If it doesn’t help, you will need to replace it.

    The resolution of your photos is too low for me to view anything useful. =^..^=

    If you’d like a serious answer to your request:
    1) demonstrate that you’ve read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you’re going to ask about jams include the jam code.
    4) if you’re going to ask about an error code include the error code.
    5) You are the person onsite. Only you can make observations.

    Thanks for your reply. I am using OEM Toner Box but toner is from other cartridge. Means i have put it from top through a hole!

    Please tell me if this machine can detect empty toner and can not used again again?

    And do I have to purchase a new OEM Toner?

    Will this help?

    5500i toners have an rfid chip that the machine tracks, simply adding more toner to a cartridge that the machine has already determined is empty will not allow the unit to add toner to the developer. Just put in a new toner cartridge for the 5500i! You said that you added toner from another cartridge, what cartridge? Is it compatible with the 5500i? All Toner is not the same. You are creating more problems for yourself than is necessary.

    Re: Taskalfa 5500i Error Code C7101

    Hello

    I have several of these machines: Kyocera 5500i Utax CD1455 and error C7101 — black developer error. I searched and dug and found what causes this rather common mistake. Although the developer has a lifetime of up to 600,000 prints, sometimes even after about 100,000 shows this error and replace it? after all, the developer is 600,000, so I was looking and it turns out and this probably applies to all development teams in kyocers / Utaxach. A film is glued between the td sensor and the developer housing, which should not be there in the developer. The td sensor housing adheres to this film and the flag itself is wiped from the other side with a flag, which after some time causes deformation of this film, so that the sensor does not overlap the sensor and the toner level sensor does not read. You should remove this film (cut out) then secure the sensor so that the developer does not spill on the bottom of the developer. In this way I saved 4 developer teams. The level of sensor reading from 15 jumped immediately on 520 and the machines have been running for over 3 weeks. I will add that you can buy the developer itself and the black magnetic roller in china

    Please guide me how to set good values m
    This error means something went wrong with values of (Developer/Toner)
    the main culprit is the t/c sensor or the ID sensor on the Developer unit
    other time (real percent is not equal i.e if toner is more than developer copies will be paled if developer is more a black background will appear while text is not dark enough
    the solution
    u should have the unit refilled with a new developer and go to U131 and execute and hit start
    (make sure you have the right toner for you machine with good quality)

    or you will have to change the Developer unit
    ——————

    Few occasions the hopper is blocking toner path so you have to make sure it’s not clogged either

    First thing I’d do is run a bunch of skyshott to get all the unknown toner out of the DV unit and then put OEM toner in and run calibration. You may end up having to replace the DV unit.

If the T/C control is not capable at the DLP or there is a possibility that DLP is LOCKing by jam in the developing powder outlet etc.

(It may be accompanied by the unusual rattling sound like no engagement of gears and C7101)

1.In case of abnormal sound occurs

a. Replace the DLP UNIT .

b. Re-assemble it as referring to below attention 1.

2. In case of no abnormal sound (developing drive possible)

a. Check the firmware Ver.and version up with most updated one and

replace

the DLP UNIT.

b. Re-assemble it as referring to below attention 1.

3. In case of no abnormal sound and firmware version is most updated one

a. Remove the INNER UNIT.

b. Check the CASS SHUTTER of the DLP UNIT.

c. If the parts is broken, replace the DLP UNIT.(Fig.1)

d. Re-assemble it as referring to below attention 1.

4. In case of not applicable above 1,2.3

a. It is possible of error at the DLP motor. Check the DLP motor.

Fig.1

CASS SHUTTER

C7101(Toner Control Sensor Error)

attention 1

The measure against below condition was taken after 2011 Oct. production. Therefore,

below action is not necessary if the production month is Oct. and after.

Break (bend)

When pushing in the CASS LOCK release LEVER at the INNER UNIT, there is a

case not to push in smoothly.

In that case, without pushing in by force, re-install the INNER UNIT while shifting it

by right-hand side and fix.

If it pushes into INNER UNIT forcefully, the lock release cannot be done normally,

C2101, C7101, and unusual sound occur again and DLP UNIT may damage.
