Need part numbers to order parts

Expensive if bought from the item manufacturer as a spare part

Google search "replacement battery for coma solar powered led motion sensor light model no. 052-7808-4 might produce results.

Most battery packs are fairly standard but first you need to remove it in order to identify it - voltage, type, capacity in order to search further or to wade through the huge list on sites such as ebay.

yes there was a sensor switch, which can be broken and faulty that needs to be repair or replace.

Did you check the different voltages coming (or should come) out of the power supply?
When a display works, will not implicate the power supply is working correct. It is too long ago I worked with these kind of printers, but I don't think the stepper motors need a capacitor. The caps can be defect, and can cause the loss of one or more output voltages.

THANK'S

If the paper is moving freely in the printer and you are not experiencing any paper jams etc it may be possible the error is being indicated falsely.I would recommend firstly to ensure the tractor feeds on the printer are clean and free from a build up of paper dust etc. As the paper motion sensors are located on the tractor feeds.
If after the printer is cleaned the error is still see the problem may be related for a setting for the Paper Motion Threshold in the printer. this is the point at which the printer detects an error. This value is dependant on a number of factors; Paper Type, condition of the printer etc.

1. Put the printer OFFLINE
   
2. Press and Hold down LINE FEED and ENTER until TECH ACCESS ON is displayed (approx. 5 seconds)
   
3. Press the MODE button
4. Press the DOWN ARROW until TEST is displayed
   
5. Press button 1
   
6. Press the DOWN ARROW until DIAG is displayed
   
7. Press button 2
   
8. Press the DOWN ARROW until PMOTTHR is displayed
   
9. Press button 3
   
10. Press the Either ARROW to set the value to 170 and then press ENTER to save the value.
    

Once you have completed the above sequence press and hold down the LINE FEED and ENTER KEYS to turn tech access off, you can then test the printer. If the above does not clear the message try increasing the value further.
If the problem persits you may have a faulty paper motion sensor.

you need to clean paper motion sensor first,

check its connection on logic board

clean the connector of sensor,

if you can then please post u r problems with printer model then i can explain it more.

There's a paper jam while the paper is trying to exit the printer. The definition of the error is saying that the leading edge of the paper has reached the exit sensor, but the other end of the paper hasn't yet. Because it's jammed...

It could just be a regular paper jam that needs to be cleared, or it could be a faulty exit sensor or a faulty registration roller, or registration sensor. I'd try clearing the jam thoroughly, and then try printing again. If it's a recurring error then you may need to call someone to replace a faulty part...

Have the TPS sensor checked out. It should be the item doing this to your car that is faulty

Technical Services Note
MT6xx/T6xxx (All) Paper Motion Faults 11 May 1995
T645.039
If you are having problems with recurring Paper Motion Faults that don’t seem to stay
fixed by doing the paper motion sensor calibration, try the following:
· Check the back of the form along the left side to ensure there are no black (dark) areas
in the area of the tractor drive holes. (If there are, this is probably the problem. If not,
proceed on down this list.)
·
Clean the sensor on the upper left tractor then run the calibration routine again. If it’s
not better yet, continue.
·
With Tech Access ON, do the following:
Go into DIAG - Meters - Paper Motion and monitor the sensor reading with paper
installed and removed. If the reading with paper installed is in the 300 to 350 mVolt
range, change the sensor (even if it seems to run the calibration alright). A more
normal reading would be something greater than 600 mVolts for the MT691/6092 and
1000mVolts or greater in the 645/661. Don’t forget to recalibrate the sensor. If it’s
not fixed yet, try this next step.
·
Run a configuration printout and then do the following:
1. Clear the NV Ram (Tech Access feature ON)
2. Calibrate the Paper Motion and Paper Out sensors
3. Restore the configuration based on the print-out you just ran

Sensor is located below the upper left tractor item 99 below. Clean it and make sure the V is facing your holes in the paper. If that isn't the problem? see below how to meter sensors procedures...
