6 Troubleshooting This chapter helps you correct printing problems that may occur. If you experience a printing problem, you can perform several tests to find and possibly correct the problem.
Chapter 6 — Troubleshooting Checking the Power Source Press any button on the printer control panel. If there is power, the power indicator (green LED) turns on and the printhead moves to its starting position.
Chapter 6 — Troubleshooting 2 Check the area between the printhead and the printer cavity. If the ribbon cartridge touches the pivot frame, the printer mechanism needs realignment. Pivot frame Printhead at far left in the printer 3 Loosen the four screws that hold the mechanism in place using a Phillips screwdriver (see the following illustration). 4 Push the printer mechanism to the right away from the green thumb wheel.
Chapter 6 — Troubleshooting 6 Hold the printer mechanism in place and tighten the screws in the sequence shown below. 1 Top right 3 Top left 2 Bottom left 4 Bottom right Four screws hold down the printer mechanism Troubleshooting System Components The printing system is composed of four basic components: printer, computer, power source, and communications. Any one of these components can prevent the printer from functioning properly.
Chapter 6 — Troubleshooting Printer Verification If the power indicator works properly and the printer still does not print, then printer errors are noted. If any indicators light when you press the Set Page button, or the printer beeps, refer to the Printer Failure Indicators table on page 102 to determine the problem. If none of the listed conditions are indicated by the beep codes and LEDs, yet the printer does not perform properly, then perform a printer self-test.
Chapter 6 — Troubleshooting If the protocol options match, then the communications cable may be defective. To determine if the cable is working, substitute a new cable. If the PC is suspect, substitute a different PC. A defective computer dock might be another possibility. Understanding Printer Errors Printer Errors are divided into classes: • Runtime errors • POST errors, • Fatal errors (consisting of flash write errors and EEPROM block errors).

Chapter 6 — Troubleshooting 3 Press the Reset button to start the POST. When the POST starts, green Power LED will come on followed by a single beep indicating that the printer is active. Note: After the test is completed, all LEDs turn off and the printhead moves to the home position. Only runtime errors or fatal errors are reported until the next time the printer is reset and POST is performed. The printer emits beeps and flashes the LEDs to indicate the cause of any POST errors.
Chapter 6 — Troubleshooting The octal digit changes every four beeps until four octal digits are output. Only four octal digits are output since blocks are 256 bytes in size and flash can be addressed with a total of 0x7ff blocks. The segment address output is the runtime address of the flash block and not the offset of the block within flash. To obtain the block offset within the flash • Subtract 0x800 from the address output to determine the block offset.
Chapter 6 — Troubleshooting Font Module Verification A CRC is performed on the font modules, which are loaded into writable flash font memory. The calculated CRC is compared to the CRC embedded in the program module. Results are printed on the self-test report. A2D Check Current reading of the A2D sources are performed, and the results are printed on the self-test report. Nonvolatile Diagnostic Memory Verification A CRC is performed on the area of the nonvolatile diagnostic memory that has a CRC over it.
Chapter 6 — Troubleshooting A self-test is equivalent to a warm start. Both are performed when you simultaneously press Form Feed and Set Page buttons on the control panel for a few seconds. Release the buttons when the printer beeps and all indicators are lit. If you press the buttons for too long, the self-test will not happen and the printer will form-feed one page. As the self-test progresses, the indicator lights change. Internal tests are performed and the two page report is printed.
Chapter 6 — Troubleshooting • Battery Voltage, (line 13) Indicates the input voltage sampled at the beginning of the self-test. The input range must be between 7.5 and 15 V. The input voltage must be greater than 10.5 V to charge the internal battery. At 7.5 V or less, the Low Batt LED comes on and the printer enters Sleep mode. At 10.5 V or less, the Low Batt comes on but the printer still prints. • Auto Feed (line 16) Auto feed is a configurable item. Carriage Return (CR) means no auto linefeed.
Chapter 6 — Troubleshooting Head Jam History Information (continued) Heading Description Step The acceleration step at the jam. 0 means no steps were taken, 15 means all steps were taken. 1-14 indicates the printer jammed during acceleration or deceleration. The ambient temperature at the last head jam. The temperature is listed in Celsius. Position of carriage at the time of the jam in 1/720 in = 12 * step position. Divide the number by 12 to get the step position. There are 512 steps across the page.
Chapter 6 — Troubleshooting Error Log Information (continued) Heading Description ADErr EEErr Dlink Number of A2D conversion failures Number of EEPROM write failures to diagnostic block Number of software memory errors (corruption in internal memory) Number of software memory errors Llink Sample First Page of the Self-Test Note: Lines 15-18 are factory default printer settings. Take note of these lines when reading the self-test report.
Chapter 6 — Troubleshooting Sample Second Page of the Self-Test Page 2 of the self-test contains the print pattern used to diagnose printer mechanical behavior. The pattern continuously prints the ASCII characters between 33 and 126 decimal inclusive for the entire page, or until you cancel the print by pressing a button on the printer. An example of that rotating pattern is shown below. !”#$%’()*+,–./ 0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_’abcdefghijklmnopqrstuvwxyz{|}~!”#$%’ ()*+,–.
