How to solve error C-2552 in Konica bizhub c253


Lets start with the code description.
Abnormally high toner density detected cyan TCR sensor
• TC ratio in the developing machine, which is determined by Toner replenishing amount control mechanism, is 11 % or more for a given number of times consecutively.

There are a couple of things I would try before replacing the Cyan Imaging Unit. Try taking out both the imaging unity and the toner and re-installing them. Restart the machine and see if the error goes away. It may be necessary to replace the imaging unit if the error persists. If replacing the unit is required and doesn't solve the problem, it could be that you need to replace the pcb (printed circuit board) and you probably need to call a qualified service tech out to take care of this for you.

Let us know how this works out for you and keep us updated on your results.

KEF PSW 2500 Relay buzzing and audio output buzz


Have just repaired a similar problem with a KEF 2500 - relay was chattering at 50 Hz rate, buzz in speaker output.

Problem was caused by overheated / dried out Electrolytic filter cap (C52 - 47uF 63V) on the relay coil supply feed.
The overheating is caused by adjacent power supply dropping resistors which run very hot due poor design of power supply.

A service manual for a similar model is available at following link, refer to power supply section:-
http://www.eserviceinfo.com/downloadsm/35375/kef_psw2000.html

To replace,
1) remove chassis from speaker cabinet (8 screws), disconnect red/black speaker wires from main PCB spade connectors.
2) Remove 4 screws attaching main pcb heatsink assembly from face panel - lift assembly from faceplate (a bit messy , much heartsink compound between mounting faces)
3) unplug the AC 3 pin connections adjacent to the large capacitors and the 3pin connector on end of pcb (near C52), then roll assembly over the top of the audio sub-board to access underside of pcb.
4) solder connections to C52 is accessible at edge of board without further dis-assembly.
Take extreme care replacing C52, as the circuit board is of poor quality, (usual domestic electronics quality) being single sided copper without plated through holes.
The board is already heat damaged by heat buildup from power supply resistors, so the track will most likely lift and crack when disturbed- to counter this problem link the +ve capacitor pigtail to an adjacent solder pad on the same track.
Assembly is reverse of above, take care to preserve/ensure minimum disturbance of heatsink compound.

A user tip- don't leave unit switched on when not in use- heat buildup will eventualy cause it to fail due dried out electrolytic capacitors.
Poor power supply design is the main source of the standing heat buildup.

Toner problems with Konica Minolta 2450


very annoying message i agree - most likely caused by toner dust.

The printer uses a carousel to rotate the toner cartridges. Dust and toner can easily spill as the cartridges rotate. The error can appear at any time but seems to be most annoying after a paper jam or other error. It is also important to make sure that the cartridges themselves are clear of toner dust. Pay particulair attention to any copper contacts on the cartridge.

tha minolta di3510 developer unit looks the same as the unit for the konica minolta bizhub 350 but the toner sensor in the minolta unit uses a different voltage range for the toner sensor and it will throw this code make sure you have the correct unit for this machine also you can try this
go back into tech rep mode and change these settings:
select tech rep choice mode
select printer tab
select atdc sensor gain
set the value to about 165
then back all the way out to the ready screen and power the machine off then back on and replenish toner in the user management screen.
