screwdriver. Flip down the projection switches on the left and right from the standard position to the LLP position one by one.

4. Close the paper cover rmly until it clicks.

Standard (Projection switch front view) LLP CAUTION When opening the paper cover, be careful not to touch the entrance of the blade of the auto cutter. The print head is very hot immediately after printing. Be careful not to touch it with your hands. Do not touch the print head with bare hands or metal objects. The set position of the projection switches on the left and right must be identical. When this setting is enabled, the printing density may decrease. If necessary, increase the printing density or use a paper with excellent coloring properties. This function reduces physical friction by reducing the head pressure and does not guarantee friction resistance for all bad quality papers. Refer to PRECAUTIONS IN HANDLING THE PRINTER34

3.9 Precautions for Creating Applications and

Practical Operations If printing is done immediately after the paper is partially cut and torn off, the top of the next print out may be distorted. For printing after cutting, we recommend to print with the rst line empty. If you are using a serial interface that has a slow data transmission speed, streaks may appear in the printouts when you are printing graphics or gradated text, which require large amounts of data. USB interfaces may be susceptible to the effects of electromagnetic interference from the host or environment. If this is the case, try using a cable with ferrite cores on both ends, which are very ef- fective at eliminating EMI.

Take care to avoid obstruction of the paper outlet and paper jamming around the outlet during printing. If paper cannot get out of the printer, it can roll up on the platen inside the printer and cause an error. If the paper wraps around the platen, open the paper cover and carefully pull the paper out.

4.7 Precautions for Performing Printing for Which

Printing Speed Changes When printing for which the printing speed changes is performed, white lines may be printed or paper may not be fed depending on the printing conditions. To prevent these problems, change the following memory switch settings.

1. Enable MSW2-3 (buffering).

2. Increase the baud rate of MSW7-1 (serial baud rate).

3. Change MSW10-2 (print speed) to a lower level.

CAUTION Depending on the serial interface transmission speed, ambient temperature, print data duty, and other factors, changing the above settings may not eliminate the problems.42
