 Disconnect the power and interface cable.
 Remove the cover.
 Check that screws are tightened and inspect rubber belts and rollers for wear and
cracking.
 Check that the cogwheels align properly and are firmly fixated on their shafts.
 Check for missing circlips.
 Check that you can rotate the rollers over the magnetic heads when no ticket is in-
serted between head and roller.
 Enter a single ticket into the lower rear input. Turn the rear cogwheels to feed the
ticket in over the magnetic module until the rear of the ticket passes the home posi-
tion sensor. Check that you cannot easily rotate the rollers over the magnetic heads.
 Turn the rear cogwheels the other way around and check that the ticket goes up to
the upper rear upper track.
 Forward the ticket again as much as possible while checking that is passes between
the rollers after the cutter without slipping.
 Hold down the plunger of the front solenoid and turn the largest of the front cog-
wheels on the right.
 Check that the ticket enters between the platen and the printhead without slippage,
then remove the ticket.
 Check the position of the springs. They should be as close together as possible.
 Remove any dust that has fallen down into the printer.
 Make a weekly maintenance.
 Reassemble the printer.
 Make test tickets while watching the tickets move through the printer. If ticket trans-
port hesitates, check the width adjustment of that part of the ticket track.
After completing this, the printer is as good as new!
