4.2 Print Head Pressure Adjustment Knob There are two conditions that will need to adjust the print head pressure. 1. Print with thick media If media thickness is larger than 0.19 mm, the larger pressure is required to get good quality printout.
4.3 Mechanism Fine Adjustment to Avoid Ribbon Wrinkles This printer has been fully tested before delivery. There should be no ribbon wrinkle presented on the media for general-purpose printing application. Ribbon wrinkle is related to the media thickness, print head pressure balance, ribbon film characteristics, print darkness setting…etc.
Page 48
Adjust the print head pressure adjustment knob Adjust the print head pressure adjustment knob Left knob Middle knob Middle knob Right knob The print head pressure adjustment knob has 5 The print head pressure adjustment knob has 5 levels of settings. Clockwise direction adjustment levels of settings.
4.4 Z-axis Mechanism Adjustment Knob Z-axis mechanism adjustment knob Fixing nut Indicator (The default position is set at the lowest line.) For narrow media, If change the print head pressure adjustment knob setting can’t get the printout without ribbon wrinkle, the Z-axis mechanism adjustment knob should be adjusted to get the satisfied printout.
Page 50
2. Please be noted that print head right pressure find turn should be done by try-and-error. Rotate the Z-axis mechanism adjustment knob clockwise for a few degrees by screwdriver and print again to check if the ribbon wrinkle remains. If the wrinkle still remains, please turn the Z-axis mechanism adjustment knob clockwise about 1/4 circle each time for adjustment.
5. MAINTENANCE This session presents the clean tools and methods to maintain your printer. 1. Please use one of following material to clean the printer. Cotton swab (Head cleaner pen) Lint-free cloth Vacuum / Blower brush 100% ethanol 2.
Page 52
Note: Do not touch printer head by hand. If you touch it careless, please use ethanol to clean Please use 100% Ethenol. DO NOT use medical alcohol, which may damage the printer head.
