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

minolta di350 reset all counters

March 21, 2009

In this mode you can reset all counters to 0.

How to reset all couters:

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.

how to maintenance code reset :

utillity-stop -0-0-stop- 01-3-start-3-start-3-start.on display will be  apear 00 .Press now ‘clear’ key .on display will be apear 40000 .Touch  ’start’ and reset panel .That’s it !

code J– reset :

open the right door- check tension spring and lever’s movement  in right side of the fusing unit . The tension spring is usualy too weak , so change it with new one , more strong. Then clean sensor and check correct highness of actuator(in sensor  frame). If the actuator is too down -loosen screws of fusing unit , push up the fusing unit-in right side  and tight screws.

Fix minolta di 152, minolta di 183 in same way.

spilling toner from imaging unit :

-remove the imaging unit ond open it in usual mode.

-remove the cover of the developing unit

-check in right (back) side of magnet roller -condition of the mylar .If  is broken change it with a new one .you cane made new one from thin OHP film.Insert it under doctor blade and put here  some adhesive (super bond, super glue). Meantime  clean charging corona , charging grid , and replace drum in was broken from old mylar.Check also or replace the roll :
