Ultra electronic Sprinter manual Refitting the cover, Setting up your new thermal printhead

(3)Check that the springs at the back of the printhead assembly are neatly compressed and are not bulging outwards or inwards. If they are bulging the assembly will have to be removed and refitted again until they remain neatly compressed.

(4)If a head bar was fitted, refit it with its two securing screws ensuring that the left hand screw is also fitted through the terminal of the printhead earthing strap (Loctite 222 threadlocker should be used on these screws). Align the terminal downwards and in parallel with the leading edge of the chassis cover.

If no head bar was fitted, ensure that the printhead earthing strap is connected to its’ original securing point

(5)Reconnect the two cables at the rear of the printhead ensuring that the locking arms of the grey ribbon cable connector are fully engaged.

(6)Referring to the rear of the Test Card which was supplied with your new printhead, set the ‘density hex value’ as

indicated on the rear of the card.

N.B. There are two different diagrams on the rear of the card (see right), compare the cicuit board in your printer against the two diagrams and decide which diagram is relevent to your printer. Then change the settings on your printer to match those marked on the diagram on

your card (in the high-lighted area). Do not change any of the unmarked switch positions.

5.Refitting the cover

Refitting of the case is the reverse of removal.

Ensure the printer interior is free of debris or particles.

Take care not to trap the display cable as the top cover is lowered into position.

6.Setting up your new thermal printhead

(1)Load the card cassette with cards and refit into the printer. On Flip models ensure that UR8 Dye-Film is fitted.

On all other models fit UR1 Dye-Film.

(2)Reconnect the mains supply and switch on the printer.

(3)After the printer has finished its initialisation sequence (all lights have stopped flashing and the printer is silent), press the internal test button at the rear of the printer (approx 1cm above the Centronics port). After a short delay the printer will start to print a test image.
