One of my customer has a ricoh mpc3500. It's been working fine since installed before 3 years ago. But now

it displays sc460 occasionally. i'll appreciate any help.

Probably, you have problem with high voltage, clean and check HV controler ( and cables and conectors), on back side.Maybe dust.Need more info.

Hi. I've just come across an MPC 2800 that when i arrived was OK, but is reporting at least 10 sc460's in the past 24 hours and am wondering if you ended up finding a fix.

Manual says problem with HV power supply/cabling or IOB. I've re-seasted all cabling to and from these boards and checked fuses for continuity etc.

Machine is up now but i fear a repeat. Any clues? Power fluctuations?

i guess it's caused by wet paper . it happened frequently while raining outside . I told my customer to change paper . it was better than before

So this could be damp paper?! I have had an MPC3500 doing this over the last few days too but it has been sitting in a very cold environment for a long time. I will have a go with some new, warm paper and see if that helps?

I don't get the error code until I run the first copy, the machine warms up and gets to ready fine.

Weird.

I had this intermittant fault - try resoldering all the components on the small board located beneath the transfer roller ( mounted on right hand side opening door flap, it is the HV board for the transfer roller and can have dry joints. Thanks to Neil for helping me with this

what i think this is Separation power pack output error

OR 1. Replace the high-voltage supply cable.
2. Replace the high-voltage power supply unit.
3. Replace the IOB.
