XPM 200HR Thermal Printer Family HENGSTLER ® 8.2. Graphics/Bar Codes Printing graphics rather than text consumes more current than printing only text. Typical textonly printing is considered to be 12.5% coverage on average, while graphic printing varies from 25% to 50% average, consuming 2X to 4X the average current. Printing bar codes is in the same category, and draws about 4X the current of text. Both should be avoided or minimized to reduce current draw. In terms of current draw, it does not matter whether printing is done using the printer’s internal character set or the via the driver. 8.3. Reverse Printing Reverse printing should be avoided, since everything that’s normally black becomes white, and vice-versa, drawing (in average text) about 8 times the current. 8.4. Dot History Factor Dot history monitors previously burned dots and reheats them for a shorter time to prevent blooming and excessively black areas, thereby decreasing total current consumption. Using dot history and minimizing the main burn time will reduce average current draw. Please refer to the XPM 200HR Emulation Command Set Reference for the specific command sequence. 8.5. Burn Time Correction The XPM 200HR family of printers include a feature that will adjust burn time automatically depending upon ambient temperature. Burn Time Correction allows the adjustment of these burn times to “tune” the printer to maximum performance for any given paper, thereby improving print quality but having little effect on current consumption. If current draw is truly critical, reducing these values will reduce current slightly at the cost of lower contrast in the printout. Please refer to the XPM 200HR Emulation Command Set Reference for the specific command sequence. 8.6. Multi-Strobe Factor This feature is the only XPM 200HR software feature that will reduce peak current. When this features is turned on, only one side of the printhead is fired at a time, reducing the peak current by a factor of two, but having virtually no effect on average current. This is very useful if your power supply has a restrictive maximum current, but slows printing. Please refer to the XPM 200HR Emulation Command Set Reference for the specific command sequence. 8.7. Print Density Adjustment Increasing print density will improve print quality, but at the same time will increase average current. Therefore Print Density is always a trade-off between these two characteristics. Use the lowest print density that is visually acceptable to minimize current draw. Please refer to the XPM 200HR Emulation Command Set Reference for the specific command sequence. Part No. D 690 074 Mod. No. 4 300113 LEV page 26 of 32
XPM 200HR Thermal Printer Family HENGSTLER ® 9. Troubleshooting Symptom Possible Cause Corrective Action No LEDs light on printer 1. Power not connected 2. PCB mounted fuse blown 1. Check line cord and outlet 2. Return printer for fuse replacement; not field replaceable LEDs flashing See Section “LED Indicators” See Section “LED Indicators” Printer prints blank paper 1. Paper inserted upside-down 2. Wrong side of roll coated Print quality poor Baud rate, other configuration setting changes not implemented after use of Configuration Tool 3. Printout positioned outside printable area by “set” command 1. Print density set too low 2. Printhead not fully lowered 3. Incorrect paper type for XPM 200HR printhead 1. Printer was not reset after changes made with Configuration Tool. 10. Maintenance The XPM 200HR printers require very little maintenance. 1. Invert paper roll 2. Invert roll as test, have paper made properly 3. Change “set” command settings to relocate printout 1. Adjust print density, other burn time adjustments. 2. Lower printhead. 3. Procure and use correct paper. 1. Reset printer. Consider enabling “Automatically reset printer” option on “Tool Settings” tab of XPM 200HR Configuration Tool. Note: Discharge your body’s static electric charge by touching a grounded surface before performing any maintenance procedure. Do not touch the connector pins of the printhead cable with your bare hands. Note: Do not touch the surface of the thermal printhead. Mechanical stress or shock (including foreign contamination) to the surface of the printhead substrate should be avoided to prevent printhead damage. Clean the XPM 200HR whenever it becomes dusty, as paper dust will reduce the friction of the platen and cause the print quality to deteriorate. • Open the print mechanism by using the Printer Access Control. Remove any paper, if necessary. • Clean the platen with a special platen cleaning agent and a lint-free cloth. DO NOT use alcohol to clean the platen because alcohol hardens the platen material. • Gently wipe the surface of the thermal printhead using a cotton pad soaked in METHANOL to remove dust on the heating elements. DO NOT use sandpaper or other abrasives. • Dry the XPM 200HR mechanism completely and reload the paper. Note: Condensation should be avoided. If condensation occurs, do not power the printer until all condensation has dissipated. Part No. D 690 074 Mod. No. 4 300113 LEV page 27 of 32
