Ricoh Afício 2045 - SC990

[Michael]

Does anybody know what can I do to solve the sc-990 code in aficio 2045?
I've already changed the hard disk.

990 quite often is to do with the procon. If you look on the smc it will show you a code.

Check the drum, charge roller and laser unit. Normally either pming or replacing the pcu gets rid of the code.

I have and many others i know have had the pcu bang on 150k or just a little over call this sc code.

[Fearless V K]

These machines want their drums at 150K. SC990 is usually a good indication of a bad drum.

I get this with a non original drum or a drum way past its sellby

[Cipher]

procon.c being logged is most common but SC990 can also cover a broader range of faults caused by a different combinations of functions and settings.

Some instances are fixed in firmware some are not.

[Michael]

I changed the pcu unit, the hard disk and the code still appears.
Is there anything else that i can do?

[hosennet]

Change the A2309510(OPC Drum) or B0822203(PCU UNIT)
Do SP MODE 2-805
