Section 4. Cleaning and Maintenance

NOTE: The PRINT potentiometer adjustment will affect the darkness in all of the command code speed ranges, i.e. if the PRINT potentiometer is adjusted for lighter print, the darkness will be lighter in all speed ranges selected by the command code.

PRINT SPEED

The other method of controlling print quality is by controlling the speed at which the label is printed. This adjustment is made only on an individual label basis using the Print Speed command code. For more details on this command, see the “e” and PRO 3Printer Programming Reference. Changing the print speed allows the user to control the amount of time allowed for print element cooling before the media is stepped to the next print position. It is especially critical when printing “ladder” bar codes (bar codes printed with the bars parallel to the print line). When printing a “ladder” bar code, it is important to allow the head to cool sufficiently before stepping to the next position. If it does not have sufficient time to cool, the bar will be “smeared” on the trailing edge.

The Print Speed can be set using the LCD panel or with the Print Speed software command. The software command will override the any setting entered using the LCD panel.The other method of controlling print quality is by controlling the speed at which the label is printed.

This adjustment is made only on an individual label basis using the Print Speed command code. For more details on this command, see the “e” and PRO Printer Programming Reference.
