From looking at the manual it looks as if you have a faulty thermistor. When warming up, it has to heat up to at least 60 degrees. If it stays lower then 60 degrees celsius for over 35 seconds and doesn't reach 60 within that time frame then that would cause the open heat error that is happening on your machine.

How do i fix the error message set pcu correctly on my ricoh aficio sp c811dn


Turn the machine off. Open the access door and remove the cyan photoconductor unit. Check the contact pins are straight and undamaged. Gently reinsert the unit. Turn the power back on. If the machine still does not recognise the pcu is inserted it is probably damaged and needs replacing. How many copies/prints has your machine done?

I have a ricoh spc820dn printer and got error message SC553 any ideas how to clear?


Hi, I'd be glad to help you.

SC 553: Pressure roller fusing lamp over heat
The detected pressure roller temperature stays at 200°C or more for five seconds.

It could be:
• Defective PSU (power supply unit)
• Defective BCU (The BCU generates the FGATE signal based on the registration sensor ON timing).

Last time I had this error (over a year ago) on this model, it was the PSU.

Best of Luck
