Error code SC543 means Fuser Overheat Error 1, Hot Roller Fusing Lamp Overheat. This has happened due to faulty or dirty/worn out heating roller thermistor. Try turning off the copier for 1-2 hours and let it cool down. Now check if error disappears. If error is still there you'll need to clean/replace the thermistors. Hope this helps... If it does please do not forget to accept the solution or post back for assistance.

    To access the thermistors remove the fuser cover. Check if they have any toner deposit on them. There are 2 thermistors on Ricoh printers/copiers, check for the connections on both the thermistors(one on left

I have an all in one and I can print, scan, and

On the printer press setup-->choose tools option-->under tools-->choose print a fax test page.

Find out how is the printer connected with the fax line.

Note:- Line 1 at the back of the printer should be connected directly to the wall jack of phone line.

Now Follow the instrcution below.
  1. Send a one page black and white text fax to 1-888-hpfaxme (1-888-473-2963).
  2. When your fax is received by the HP Test Fax Service, They will generate a return fax to you within five minutes confirming that they have received your fax. This verifies that you can both send and receive a fax with your fax machine.
If you do not receive a return fax within 5-7 minutes, there may be a problem with the setup of your fax machine. Note:-The most common cause of failure is that the fax number set in the Fax Header on the machine does not match the number of the phone line connected to the fax. Also, ensure that the fax header contains the full 10-digit telephone number of the fax machine, including the area code.
