It is possible to get a false “good” reading if the sensors are too close to the feed rollers.

Functional test of the sensors From each of the laminators, upper and lower, remove the transfer guide and the laminate patch, if any, beneath it. The sensor should read high, around 250. Replace the guide, and the sensor should read no lower than 180. If lower than 180, move the sensor board away from the transfer rollers, to the left, diagram below.

Complete the test by running laminate onto the rollers (press the LAMINATE button). The sensor should read below 20. Adjust sensor board to correct.

Caution • The sensor board must be symmetrically positioned relative to the transfer rollers. with its attachement screws central in their slots.

Heater Temperature : This is the set point - temperature desired - not the actual temperature. For actuals, see Sensor Data, preceding page. NOTE: Temperatures are monitored by thermocouples at the core of the heated rollers. Surface temperatures may differ significantly.

Caution • Do not set the temperature ABOVE 180°C, or BELOW room temperature

Line Voltage: If Auto is selected, the printer guesses line voltage based on line frequency, assuming that 110V will be @ 60Hz, and 230V @ 50Hz. If this isn’t the case in your locality, the printer will guess wrong, and you should set the voltage manually.

Note • Running the printer at 220V, 60Hz in Auto mode may cause premature failure ofthe heaters. Running the printer at 110V, 50Hz in Auto mode may cause abnormally long heat-up time and poor temperature control.

This setting has nothing to do with the printer power supply. Like the laminator heaters, the power supply can handle any voltage from 110V to 230V, so an incorrect setting here will cause no immediatedamage.

Correcting Laminator Problems
Laminate Station Adjust

Start > Printers (or Printers and Faxes) > Right click Zebra P640i > Properties > Device Settings > Printer

Adjustment > Laminate Station Adjust

Length Adjust (mils): This is the length of the laminate “patch”. If the patch is too long, decrease this number, and vice versa.

Horizontal Offset (mils): Adjusts laminate placement on the card.
Problem

Laminate bunches up outside the cutter assembly, having missed the feed slot. This can happen to either upper or lower laminates. It is probably a cassette installation problem, such as:

1.Failing to latch the cassette

2.Out-of-square scissor cut on the leading edge of the laminate

3.Leading edge of laminate not reeled in even with the lips of the cassette. Reference Section 2, Media Handling.
