Question about Minolta DiALTA Di520 Laser Printer

1 Answer

Di520 missing 24VDC - are schematics available for PU1?

My copier has a 0070 error and in investigating I find that the DC power supply appears to be missing one 24VDC line that runs M21 and others. I am hoping that the schematics are available for this PCB, but the download that I have found does not contain that particular one.

Change Sub Hopper Toner Replenishing Motor.It is the tipical malfunctions,the service manual not specificy this problem.This motor is energized for the toner replenishingtime witch is calculated based on the ATDC sensor output voltage T/C ratio and the size of the paper being fed trought the copier.

Hi, I believe this error occurs when there is no 24 volt supply to the PCB. Go back and check you have plugged all the connectors back in correctly.

Thanks

Supply memory error


Remove cartridge, observe a small chip mounted on cartridge shell..This chip calculates the approximate toner levels, once its reached "Zero" printer says cartridge empty/low replace it.. If the memory is not detected due to any reason printer will say supply error or 10:xx supply error..
Replace this memory if available( locally its available ) or replace the cartridge.. Very few cases same error appears with faulty DC controller..
Ex supply memory:

Hello. 0B000D error during start-up indicates a 24VDC failure. This is generally caused by a failed DC power supply. There are 2 types of power supplies - 1 for the 1050C series and 1 for the 1050C Plus series. They can both be found at: HP Designjet 1050C 1055CM repair parts

The intervals of zero-cross signals deviate from the tolerance range while
the fixing heater is supplied with power.
Main cause The wiring is faulty (short circuit, open circuit). The main power supply
PCB is faulty. The DC controller PCB is faulty.
Making Corrections
1. Connectors
Are the connectors J205 on the main power supply PCB and the connector
J308B on the DC controller PCB securely connected?
(zero-cross signal: J205-7 <-> J308B-1)
NO: Connect the connectors securely.

2. Main power supply PCB, Main controller PCB

Try replacing the main power supply PCB. Is the problem corrected?
YES: End.
NO: Replace the DC controller PCB.
