c0700 on minolta di350, di250
June 3, 2009
-toner motor is unable to rotate the toner bottle= The most likely cause is wrong pointing of toner bottle
Solving:
turn of the copier, pull out the toner bottle(don’t rotate the bottle
turn on the copier :
1. hear the noise behind the copier then- c0700 = the toner motor or toner rotate mechanism was broken -you must change the toner rotate mechanism or change all (motor +mechanism) with a new toner motor from EP 1050/1054-it works perfect.
2. c 0700 code appears immediately : first -check and repair the toner rotate mechanism-see above-
:second- replace the blowed 1A fuse on PWB-A with new one
turn on the copier — everything seems ok ? insert toner bottle in correct position
bizhub 250/350 code c2557
April 25, 2009
Troubleshooting for bizhub 250/350 are generally the same like DI250/350 the major difference is this code : 2557
Code usually appears when the meter count of drum and developer (in service mode) was reseted without changing deleloper followed by F8.
how to reset:
-the simplest way is to change developer and run F8.
-without change the developer:
—First : add a spoon of toner in dev. unit and instantly run F8.
—Second (if first way was not good) : in service mode-level history-atdc,There you will see displayed the current value of ATDC. Usually this value should be approximately 13 %, but after resseting it becomes 5-6 % and comes into contradiction with the presetting value in tech rep choice-printer- ATDC gain (155).
So, increase the concentration of toner in developing unit adding little amount of toner or decrease or increase the default value (in tech rep choice-printer - ATDC gain) to match the actual concentration in developing unit.
bizhub 420 code reset-service mode
April 22, 2009
how to enter in service mode when error code appear?
turn of the copier -main switch.
press and hold utility key and turn on the copier and still hold utility key until "trouble reset "appear on the screen.
now you can enter in service mode (without uti/counter,details), only code

bizhub c451,c 550,minolta c650 trouble
March 28, 2009
Jam in DF611:
-on 2-nd side:
Check mylar on the 2nd transport guide plate.
Replace the damaged mylar p/n : 9J07 4703 01
-on 1st side:
- put the tension spring of feed roller in lower position.
- ckech the sensors inside DF611 case and use some adhesive (super glue, super bond) so that the sensors cases will be hard-set.
P21 warning :
- color shift in main scan direction
the amount of color shift is different between front and back side. Color shift occurs at 1 to 2 mm in the worst position.
bizhub C650/C550/C451 (FW Ver.6B only)
The problem will be observed when below 2 conditions meet. However it is not always but it depends on the gain of image density sensor (IDC).
1. When MFP returns from sleep mode within 8 hours from the last image stabilization.
2. In case MFP detects temperature change in printer head at more than 2 degrees from the last regist control when returning from sleep mode.
<Cause>
Regist control, which takes place in above condition, is carried out with improper sensor gain setting.
- P-21 is displayed when the sensor gain is low for the MFP to detect toner pattern.
- Color shift occurs when MFP miss-detect toner pattern due to improper gain setting.
How to recover the problem:
-Apply FW Ver.6M or later
- Turn off/on the main switch
- Carrying out image stabilization

di2510/di3510 trouble
March 5, 2009
abort code and restart after power-up:
-check if the CF card is inserted properly
-if CF card it’s, OK -need to reset BRAM:
next to CF card are INI jumpers.
-turn off the machine, pull the jumpers off and cross the pins to the far right and the middle in the verticale direction.
-power ON for 20 seconds then power off.
-remove jumpers and put them back in the original position.
power on.
How to reset C0500 code :
- open the right door
-in the small hole on the right side of the control panel(same as DI 350,di351)press the soft initialization
- When the dot appears on the LCD after reboot, press 3 key.
-enter the service code (default 0000000)
- The mode will change to the initialization screen.
-Choose trouble reset.
-after reboot close the right door
-if same trouble appear again- check the thermal fuse or thermistors(heat sensing elements) or replace the fusing unit.
Light copy on ADF (DF):
-clean with alcohol the optical unit (original glass, mirrors, lamp, lens)
-use the two screws in rear side of DF to correct the position of DF againts original glass.
-pull out the imaging unit and clean the frame glass of laser unit.
