What causes the cf 910 to give c0000 and c0042

C0000
Main Motor malfunction
- The Main Motor (M1) Lock signal remains HIGH for a continuous 1-sec. period at any time 1 sec. after the Main Motor has started turning.

NO WAY That machine is very, very old. May Be ?????? maybe Windows 95 maybe.

Main motor not turning. Check for a major paper jam in the fuser unit. Open the front door and on the left side is the fuser assembly. Push in the green knob and turn the fuser. It should turn rather easily. If not it is jammed. That is the most common cause. Other than that you would need a technician to determine what assembly in the machine that has locked up and thus preventing the main motor from turning.

Hi! I just had the same problem with my Sony A100, when I tried two different CF cards. Thinking the camera is broken, I checked online camera repair sites and also called Sony directly. Sony's flat rate, and that of PrecisionCamera is $228 to fix CF card failure. Then my daughter said, "the CF card in my room works fine in the camera" - and lo and behold - it does. The CF card that works is brand PQI and is marked Hi-Speed 60 2Gb. The cards that do NOT work are marked SanDisk Ultra II 1.0Gb and SanDisk 128 Mb. So my advice is, before you give up on the camera as broken, try a number of different CF cards first.

The second cause of CF failure is if someone has pushed a CF card in the wrong way. That can bend one or more of the tiny metal contact pins in the CF socket in the camera. Look carefully to see that all the pins are straight up. [I don't know how one can straighten these pins, or if the whole socket would need to be replaced...but at least you can determine the cause of the CF failure.

Best regards - Michael

I have seen the green screen problem a few times before and this was caused by corrupted data / software or an error in booting up.
If you can't turn any TomTom off then perform a reset by inserting a paper clip into the rest hole and give 1 short press of the reset button ( it's a tactile switch so you should feel it click ) then try switching the TomTom on again the normal way. ( reset buttons are normally found through a small hole underneath the TomTom ).
If the TomTom does switch on but continues as before with the loading up problem , then it's best to format and reload all files from your backup copy.
A RED CROSS indicated a loading fault / corrupted files / incomplete files / corrupted or damaged media . ( media , meaning SD card or hard-drive )

Subject:
C0030 code is displayed and will not reset. The C0030 is referenced to the developer drive motor for the 4 developer units. developr motor is binding
hope that helps
