I went back out today to drop off loaner(table top) & ck the line voltage. I thought about the main switch & held it while copying & initially it seemed to work. When ck'g line voltage initially did not see any changes even when Copier shut down & rebooted. However one time the voltage shot up to 200 volts (meter leads plugged in at copier) . When ck'd at outlet could not duplicate??? Did notice a tension spring missing on transfer roller and broken piece from transfer unit preventing front side of transfer unit from possibly seating firmly. Did remove broken piece had no spring problem still there. Did re-ck error codes and there were (8)C0210 codes since I cleared memory yet the copier never displayed them I have a junk machine for parts mainly PCB's wondering which it might be. Most problems with this copier have been operator caused, not sure if it's the same cause what that would be.
Thanks!!!

Since you have noticed c0210 error codes, which is a failure for the control panel to communicate with the main pcb this may be the source. There is a power button on the control panel and if it did not communicate correctly with the main pcb it could cause the symptoms you describe. I would start with replacing the control panel and also reloading the firmware from a non-turbo pack update. Normally, pressing the power button during a copy job would not shut down the unit as you have described it would let the current job finish. If replacing the control panel and updating the firmware does not correct the situation I would go for the Main PCB.

I presently have the control PCB removed; that being said even with the fax PCB option removed the led on the fax button is always lit???
Thanks???

Check the ribbon cables to the fax and/or optional printer PWB. I've had some very strange symptoms from a pealed back contact on the ribbon cable:

CS-3035/4035/5035 Falcon II: Can't access service mode. Can't download fax firmware. Can't access Fax Defaults in the System Menu (only the double beep). Can't access Fax Reports tab in the Fax screen (button grayed out). "Cover Open" indication when no covers are open. "Please Wait. Cannot be combined." when attempting to fax out. Ribbon cable from the fax control PWB to the main control PWB is damaged by removing the cable without releasing the clasp. Trim off the damaged end, or replace the ribbon cable (3CM27010).
