5.2 Printing Paper Use the paper shown in the following table or paper of the same quality.
5.3 Manual Setting of Memory Switches Memory switches are used to set various printer settings. The memory switches can be set manually (set by hand on the printer) or by commands. This section explains how to perform manual settings. Memory switch settings are done in memory switch setting mode or virtual DIP switch setting mode. In the memory switch setting mode, you can set the values for MSW1 to MSW10. In the virtual DIP switch setting mode, you can set the values for MSW1 to MSW6.
Virtual DIP switch setting mode While paper is loaded, press and hold button 2 while turning the power on. Enter virtual DIP switch setting mode. FEED • Press button 1( ) to select a memory switch number. (Switches cycle in the following order: MSW1 → MSW2 → … → MSW6 → MSW1) • Press button 2 ( ) to move from switch 1 towards switch 8. (The selection loops from 8 back to 1.) • Press button 3 ( ) to change between ON and OFF. • Press button 4 ( ) to go to the save settings menu.
The function of each memory switch is shown in the following table. (Shaded values are factory settings.) Switch no.
Switch no. Function OFF ON MSW6-1 Act. For Driver Invalid Valid MSW6-2 Character Space Invalid Valid MSW6-3 Reserved Fixed — MSW6-4 Reserved Fixed — MSW6-5 Reserved Fixed — MSW6-6 Reserved Fixed — MSW6-7 Reserved Fixed — MSW6-8 Reserved Fixed — Function Initial setting Setting value *2 Switch no.
Notes: *1: If print data is very dense, the print head is hot, data transmission is slow, or some other conditions, the motor and printing may occasionally stop which causes white stripes in the printout. To print high-density data, set MSW2-3 (Spool Print) to ON to reduce striping, although this increases the time before printing starts. For a serial interface, increase the transmission speed to prevent the motor from stopping.
