Code

E010

Description

Paper not reaching fuser transport sensor: Paper which has passed the fuser unit does not reach the fuser transport sensor.

Remedy

Open the jam access cover. Is there any paper on the transport path or in the fuser unit? ? YES ? Remove the paper. NO Is the fuser transport sensor working? (Perform the input check in the test mode: 03-[FAX]OFF/[7]/[C]) ? ? NO ? 1. Check if the connector of the fuser transport sensor is disconnected. 2. Check if the connector CN332 on the LGC board is disconnected. 3. Check if the connector pins are disconnected and the harnesses are open circuited. 4. Check if the conductor pattern on the LGC board is short circuited or open circuited. 5. Replace the fuser transport sensor. 6. Replace the LGC board. YES Is the transfer belt working? ? ? NO ? 1. Check if the connector of the transport belt is disconnected. 2. Check if the connector on the transport motor driving PC board is disconnected. 3. Check if the connector CN341 on the LGC board is disconnected. 4. Check if the connector pins are disconnected and the harnesses are open circuited. 5. Check if the conductor pattern on the LGC board is short circuited or open circuited. 6. Replace the transport motor driving PC board. 7. Replace the LGC board. YES Is the drum separation finger solenoid working? (Perform the output check in the test mode: 03-111,161) ? ? NO ? 1. Check if the connector of the drum separation finger solenoid is disconnected. 2. Check if the connector CN339 on the LGC board is disconnected. 3. Check the installation state of cleaner. 4. Is the relay connector connecting the cleaner unit and the equipment disconnected or stained with toner? 5. Replace the drum separation finger solenoid. 6. Replace the LGC board. YES Is the registration sensor working? (Perform the input check in the test mode: 03-[FAX]ON/[4]/[E]) ? ? NO ? 1. Check if the connector of the registration sensor is disconnected. 2. Check if the registration sensor is installed correctly. 3. Check if the registration actuator is operating properly. 4. Check if the connector CN341 on the LGC board is disconnected. 5. Check if the connector pins are disconnected and the harnesses are open circuited. 6. Check if the conductor pattern on the LGC board is short circuited or open circuited. 7. Replace the registration sensor. 8. Replace the LGC board. YES Is the registration motor working? (Perform the output check in the test mode: 03-108/158) ? ? NO ? 1. Check if the connector of the registration roller clutch is disconnected. 2. Check if the connector CN341 on the LGC board is disconnected. 3. Check if the connector pins are disconnected and the harnesses are open circuited. 4. Check if the conductor pattern on the LGC board is short circuited or open circuited. 5. Replace the registration roller clutch. 6. Replace the LGC board. YES Check if there is any abnormality in the space between the registration motor and the registration roller (metal). Check if the registration roller (rubber) is rotating smoothly. Check the condition of the registration roller at the horizontal transport section and clean or replace it. * If the error [E010] caused by a paper jam underneath the drum cleaner often occurs due to an insufficient paper separation from the photoconductive drum, set a smaller value in the code 08-841, and see what happens. At this time, however, pay attention to the transferability at the leading edge of the paper since this transferability can be slightly narrowed depending on the environments and conditions under which the equipment is placed or the media type of the paper used. (Refer to 3.6.1 in this manual about the details of the code 08-841.)

a dryer drum usually rides on rollers. when center of roller wears out then they start to get noisy

change your feeder unit

The Error code E010 means that there is a drag on the main motor. I would look in the fuser unit & see if the lower fuser roller is damaged or that the cleaning web is wraped around the upper fuser roller. Also try to turn the fuser. You may have a siezed ball bearing. Also, try to remove the drum unit and close the door and see if the code is gone, if so you have a problem with the drum unit, but I would say it is in the fuser unit...... Good Luck

E078 secondary transfer roller drive
mechanism fault

Possiblle causes:
Check the connector of the roller drive sensor.
Check the connector of the roller drive clutch.
Replace the main drive assembly (roller Drive
sensor).
Replace the drum cartridge (roller drive cam).
Replace the DC controller PCB.

The manual says that this is a chage roller leak.
Means the the high voltage is arching to ground or drum somewhere....usually pinhole in chage roller

You didn't include a model number, and "no" cleaning it and/or blowing it off won't help you -in fact may make things worse. The "Green roller" you talk about is the drum, it needs to be replaced - unless it's part of the toner cartridge, then that's all you need to replace.

try to check your connection form your printer and if possible try reinstall the printer driver then try to run again the printer.

I have a Canon Color Image Class MF 8180C with a system error code E078 - Trying to understand what it means and how to clear. Any ideas?

A E010 & E014 have to do with the main motor drive. You may have a drum blade that has flipped or it could be that the center screw that locks the drum to the drum shaft is loose ( just tighting screw- you can also get blank copies as well. The E014 deals with the fixing unit, you have to make sure it is spinnig freely. It could be that the lower pick off claws have dug in to the lower fixing roller, or the ball bears are siezed or the web is rapped around the upper fixing roller or a bushing is broken or it may be to much pressure is on the UFR from the web... Just a few ideas.. Good Luck
