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-printerATDC 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. This procedure is logical and it works but requires some patience and experience.

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.

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

bizhub 420 c2403 February 25, 2009

Trouble code: C2403 (C-2403).

PROBABLE CAUSES: 1. When an empty toner bottle is rotated while removing it from the machine, the alignment tab goes out of home position. Then, when a new bottle is inserted, it does not insert correctly and it does not rotate —pull out and insert it correctly —Push again(until clack) toner bottle after insert it. 2. Toner sensor position ps28 contaminated with toner— use vaccum cleaner and clean all parts around toner bottle esspecially ps28. 3.Defective toner bottle 3.Defective toner rotate mechanism claws

Note : To reset C-2403 after replacing the toner bottle, perform the following: a. Power OFF main SW, inside front door.

b. Slide the toner bottle cradle and remove spent toner bottle. c. Prepare new toner bottle per instructions and place toner bottle in the cradle (line up the two notches at the rear so the cartridge is laying level in the cradle). d. Turn bottle completely around and line up the arrow at the 12 o’clock position clockwise or counterclockwise and push cradle in and lock toner door. e. The power should be re-enabled to ON while holding the Utility key; the Konica Minolta blue screen within 2 minutes, then the white screen with Trouble Reset. Touch and OK will appear. f. Power OFF/ON and should go to Ready. This procedure may have to be redone several times. 2. Toner bottle is not turning. Ensure that the toner bottle does not have any manufacturing defects. Also ensure that the pressure spring inside the pressure assembly (p/n 26TA-3332) is applying sufficient pressure when locked into place. 3. Excessive pressure from the Toner Bottle Door. Remove the two pressure springs located in toner door. 4. The toner bottle position sensor (PS28) may have shifted when the drive section on the back of the machine was removed or installed. As a result, PS28 cannot detect rotation of the toner bottle. Install a new mounting plate (p/n 50GA33161E) and stopper seal (p/n 447042481) for PS28. These parts prevent PS28 from becoming dislodged. Complete 5. between parts around the bottle guide section. Please install the Toner supply auxiliary cover countermeasure as explained in the attached Parts Modification Notice. 6. If toner bottle is not installed correctly and the customer forces it then it may cause tearing of the drive tabs on the toner bottle. This will cause the bottle not find the home position generating this error. Please ensure that the toner bottle is inserted correctly. 7. Even though the correct procedure was used p, there still may be burrson theflange tips at neck of the toner bottle.Also,PS4

and PS28 may not be sensing properly. the correct operation of PS4 and PS28. Check for burrson theflange tips at neck of the toner bottle. Remove the burrs on the toner bottle. Note : The service documentation does not include a procedure for checking PS4 (Toner Bottle Sensor) and the PS28 (Toner Bottle Position Sensor). To check: a. Enter the State Confirm mode=>’Service Mode screen’; press [State Confirmation]. b.’State Confirmation screen’; press [Sensor check]. c. ‘Sensor Check screen’; press [Check Code] and, when entering the sensor check code in 3-digit format through the copy count setting button, a state (ON/OFF) or value is displayed in the Result area. d. For the multi-mode, press [Multi Code] and enter a three-digit multi-code through the copy count setting key. When conducting the sensor check of other signal sources, repeat stepscand d. IMPORTANT : Code 57, multi-mode 2, which is not listed in the bizhub 420/500 Service Manual, is used to monitor the output signals ofPS4 (Toner Bottle Sensor), and multi-mode 3 for monitoring the output signal ofPS28 (Toner Bottle Position Sensor). These sensors are located at the rear of the hopper assembly at the 11 o’clock position forPS28 and at the 12 o’clock position forPS4. The state of these sensors will switch from 0 to 1 if the bottle is moved.
