Load the paper roll as described in the section “LOADING THE RECEIPT PAPER ROLL”...
Page 26
3. Press the lever (1) to unlatch the printhead and cutter assy. Figure 2-2 4. Lift the printhead and cutter assy and extract the finished receipt roll. 5. Unwind approximately 20 cm of paper from the new roll, then insert the roll into its compartment inside the printer.
Lower the paper compartment cover back into position. Figure 2-4 Turn on the cash register as described in the section “TURNING ON THE CASH REGISTER”. 10. Check that the paper feeds through properly by pressing the paper feed key. Calibrating the near-end-of-paper sensor When the receipt roll is inserted into the paper compartment for the first time, or when the type of roll is changed, the near-end-of-paper sensors must be calibrated: The near-end-of-paper sensor is set up at the factory to ensure correct functioning for the most...

Move the green regulation lever (1) towards the front of the cash register to receive earlier notification (i.e. for larger diameter cores). Move the lever towards the rear of the cash register to receive later notification (i.e. for smaller diameter cores). Figure 2-5 Reinsert the paper roll.
Page 29
Power off the cash register and open the cover of the central unit module (paper compartment) by pressing fully the Open key then lifting the cover upwards. Position the adapter with the reference points oriented as indicated in the figure. Figure 2 - 7 Insert the tabs (2) of the adapter correctly into their respective reference slots depending on the size of roll to be used.
If you use a 80 mm roll after having used rolls of sizes 57.5 mm or 60 mm on the printer, it is no longer possible to guarantee that a good quality of printing can be achieved. This is because, when printing, the contrast obtained from the part of the head not used by the smaller rolls, may be uneven.
