This is a common error code for Ricoh copiers, Savin and Gestetner copiers that need service. Recently Ricoh has purchased Lanier and now is naming all their new machines Lanier instead of Gestetner, Savin and Ricoh. However, the copier service error codes have remained he same.
When you get this copier printer service code it means the fuser or fixing assembly (same part) has thermistor problem. The copier fuser's thermistors help regulate the temperature of the fuser assembly. The fuser assembly on all copiers including Canon, Kyocera, Ricoh, Sharp and other brands is the part that melts the toner onto the page.
Getting back to the repairing the copier on Ricoh, Savin, Lanier and Gestetner models that have the fuser or fixing code error. The majority of the time the fusers' thermistors (Middle and read) need to be replaced. Just cleaning them will not solve the copier repair service code.
It is usually, depending upon the machine, its a 1 to 2 hour copier repair job because the copier repair service technician will need to dissemble the fuser, insert the two new thermistors, re-assemble, reset the error code and test the copier machine repair. Also, ask the copier technicians to to do a copier cleaning maintenance while on site.

A 440-1 is a black drum motor lock. The waste toner in the black pcu is backed up, more then likley. It is not easy to fix. You could replace the black pcu but it will happen again. The usual problem is oil in the main waste toner system. It clumps up the toner and clogs the part where all the waste toner comes together for entry into the waste toner bottle.

This is a fuser error code. Sometimes it is caused by a mis-reading. Use the procedure below to reset this machine.

Press the yellow "clear modes" key then pres 1, 0, 7, then press AND HOLD the red "clear stop" key until the screen changes. After the screen changes, turn the machine off at the red switch on the front of the machine. Turn it back on.

If the code comes back you will have to call a service tech to troubleshoot and replace parts.

Its a charge corona cleaning error. Try turning the power off, wait 10 seconds and turn it back on.

If that doesn't reset it, it could be the pcu, toner collected on the mechanism.

If turning it off and back on isn't fixing it, you should get a technician to look at it to see what the trouble is.
