1 Chapter 1: Outline The SCP700 Series combines both a quick, quiet and highly reliable thermal receipt printer with an impact dot slip printer, enabling printing on single or multiple sheets of slip paper of an unspecified size. The thermal printer enables receipt printing without a thermal ribbon and makes paper insertion extremely easy. The biggest advantage of combining the two printer mechanisms into one unit is that less space, only one power supply and only one port are necessary

2 Chapter 2: DIP Switch Settings The printer’s DIP switches let you change communications parameters, thermal printing density, interface type, input buffer size, and emulation. This chapter explains the settings you can make and tells you how to actually change DIP switch settings. Accessing the DIP switches The DIP switches are located inside the printer, underneath the document table. Use the following procedure to remove the document table so you can operate the DIP sw

9 Adjusting the slip printer’s dot alignment You may never have to use the procedure described in this section, but after you have been using your printer for some time you may find that the dots of some graphics do not align correctly. For example, what should look like: may come out looking like one of the following: or like this This is caused when mechanical parts of the printer get out of alignment. This happens only rarely and you may never experience it at all

10 To exit this mode, press the SLIP/RESUME button. The dot alignment adjust mode setting is stored in the memory, a pattern using the selected setting, followed by “Adjust Completed” is printed, and the printer ejects the slip paper. Note: If you press the SLIP/RESUME button without pressing the RECEIPT button after entering the Dot Alignment Adjust Mode, the printer assumes that you do not want make any settings, so it prints the message “Adjust Complete!” and exits the m

11 Hexadecimal dump This procedure prints in hexadecimal format all codes (character codes and control codes) that are sent to the printer by the computer. The printer does not execute any control codes (such as 0A - linefeed), it just prints them out. The hexadecimal dump is useful when you are writing programs for printer control. o Make sure that roll paper is loaded in the receipt printer. o Turn off the printer. o While holding down the control panel

16 Data protocol o DTR/DSR Mode Set when dip switch #1-6 is ON. Communication is carried out while handshake is performed with the DTR and DSR signals. Control is executed by selecting the DTR signal for the busy signal when data is downloaded to the printer data. “SPACE” indicates the printer can receive data, and oppositely “MARK” indicates that data cannot be received. In the ESC/POS mode, control is executed by selecting the DTR signal for the host computer’s busy signal when
