Auto Power Off
The MCP8850 will automatically switch off after approximately ten minutes of inactivity. Further data transmitted to the printer will be ignored.
The printer can be re-activated by briefly pressing the Mode button.
Replacing Paper Roll
If the paper roll needs replacing, open the paper cup lid and remove the remaining paper by pressing and holding the Mode button,
do not pull
paper through the printer mechanism
. Reel off a few centimetres from a new roll of paper and check that the end has a clean straight edge.
Slide the leading edge of the paper through the paper entry slot, with the leading edge of the paper feeding forwards from the bottom of the roll,
until you feel resistance. Press the Mode button and feed the paper through the printer mechanism. Keep the Mode button depressed until enough
paper is fed through the printer mechanism to pass through the paper exit slot. Sit the new paper roll in the paper cup and close the lid.
Should the paper become creased or out of line when feeding in a new roll, cut the end off the paper roll, feed out the creased paper using the
Mode button, and reload ensuring the paper has a clean straight edge.
Paper Tear Procedure
When removing printout from the printer, pull the printout toward the front of the printer and tear from one side to the other across the serrated
edge.
