5 System Overview - Troubleshooting
Knowing the sequence of the printer operation helps when troubleshooting the printer.
Troubleshooting utilizes the printer error buttons, error messages and printer-specific tools.
5.1 Sequence of Operations
Step Process
1 File information is received from the PC.
2 Printer compares the installed ribbon type stored in memory with the ribbon type command
that was sent from the printer. If the ribbon type does not match, the Pause button (on the
right) flashes.
3 The print stepper motor engages.
4 The card feed sensor detects the leading edge of the card and the headlift stepper engages
to disengage the input lever.
5 The card feeds through for the alignment pass.
6 The card feed stepper motor engages to queue card for magnetic encoding (if applicable).
7 The encoded data is written to the card (if applicable).
8 The magnetic encoder verifies while the stepper reverses the card (if applicable).
9 The print ribbon drive engages (if not already at the yellow panel).
10 The print ribbon sensor looks for the yellow panel.
Note: The print ribbon encoder detects the number of revolutions required to use an entire
color panel.
11 The print stepper motor engages.
12 The card feed sensor detects the leading edge of card.
13 The print stepper motor queues card to the middle of the platen roller. All stop.
14 The print headlift motor engages to the print position.
15 The print cover sensor checks for closed state.
16 The print stepper motor engages.
17 The ribbon drive motor engages.
18 The image data is burned by the printhead until the image data is depleted. All Stop.
19 The thermistor engages the printhead cooling fan to maintain proper operating temperature.
20 The headlift motor engages to the queue position.
21 The print stepper motor engages.
22 The print ribbon drive engages.
23 After ribbon advances a few encoder clicks, assume the ribbon is free of card. All stop.
24 Repeat Steps 9 through 22 for the appropriate number of color/overlay Panels.
25 Either the card is ejected from the singled-sided printer or the card feed stepper engages to
queue the card for the flipper table for the dual-sided printer.
26 All stop.
