5 ADJUSTMENTS
Whenever modules are loosened, removed or replaced, a complete adjustment and
verification cycle must be performed.
NOTE 1! — This is essential for the reliability of the printer and should NEVER
be overlooked!
NOTE 2! — Only technicians having the appropriate knowledge and experience
of the TTPM3 should carry out the adjustments.
The TTPM3 Ticket Printer/Encoder is designed for the ticket width 53.98 ±0.2 mm
according to the ISO 7810 standards.
The adjustments are done using a 02443-000 gauge-kit, and a number of the tickets that
the serviced TTPM3-unit is going to be used with.
