Troubleshooting

CMP-10 Printers: There have been a few issues reported with these printers.

1. The charger does not work. Possible cause is the tip that plugs into the printer has been detached from the cable and put back incorrectly. The "+" sign on the tip should line up with the word "tip" on the cable. When it is reversed the polarity becomes negative and when the charger is turned on it blows a fuse on the printer circuit board. This requires the printer to be returned to SuperVend Software for repair. Use super glue to secure any loose tips but make sure it is lined up correctly before applying the glue.
2. The printer does not work after being dropped on the ground. Usually when this happens the part where the paper is kept flies open and the rubber roller and the attached plastic sleeves and cogs also fall out. Unfortunately if any of the parts for the rubber roller are not put back then the printer will not function because the mechanism is pressure sensitive. The rubber roller is fixed to a metal shaft with a plastic cog and sleeve on the left side and a longer plastic sleeve on the right side. If you lose some of the parts then advise the Help Desk and replacement parts can be supplied without the need to send the printer back and forth. Note: If you are a careless person or you are accident prone then you might like to secure a large rubber band around the printer to prevent the paper section from opening in the event of the printer being dropped.
3. The printer fails to print when an orange light is flashing. Requires a paper roll to be inserted.
4. The printer fails to print even though the green light flashes OR the printed characters are not always clearly defined. This may be a simple process of cleaning the printer head. The printer mechanism is quite sensitive and will not work if any rollers are broken or missing, the printer roller holder is not closed properly or the printer head is dirty. To access and clean the printer head make sure the printer is turned OFF before opening the printer paper roller by pressing the blue button. Locate the gold plate towards the front of the printer. Use a cotton bud and metholated spirits to clean this plate. DO NOT use a soaked cotton bud which may pour metho onto the circuit board. After dipping the cotton bud into the metho simply squeeze the excess out with your fingers before rubbing the bud over the gold plate and surrounding area including the rubber roller. The object of the exercise is to clean as much build-up of dirt as possible from around the printer mechanism. Allow the metho to dry before attempting to print.
5. Make sure the battery is charged. (green light on) as this may also cause printer failure. Perform a print self test (in manual) as follows: Make sure the printer is turned off BEFORE holding down the LF button and keep it down while turning the printer ON. Release the printer ON button and then release the LF button. The printer should then print a test page. If it fails then repeat the process. If that fails the battery may need to be charged.
6. Try performing a soft reset of the handheld if the infrared signal does not work.
