CHAPTER 4 DIAGNOSTICS

If you have any problems using SENDFILE, refer to the

The following diagnostics are resident in the 9820/9830/9835 printer’s firmware ROM:

Power-Up Self-Test

Test Label

Service Diagnostics (Level 1) Data Dump Mode Diagnostics Test Mode

Off-line Diagnostics Tests Loopback Test (Level 2)

Parallel Port Test (Level 3)

POWER-UP SELF-TEST

When the printer is turned on, a test sequence is initiated. The diagnostics routine initializes the Control Board Assembly and evaluates the Printhead. The test sequence is:

Non-Volatile RAM Byte Test

Version String Mismatch

Printhead Dot Resistance

A failure in any of the test sequences results in the display of an error code on the 3 digit Control Panel Display.

An error during the printhead dot test indicates that bar code scan quality may be compromised. However, such a failure may not be evident in text printing.

Sendfile Manual on your Service CD-ROM.

Different versions of software installed.

Clearing memory with the “Reset NVRAM” function in service diagnostics.

Memory corrupt due to a hardware/software error.

If the restart flag was set during these diagnostic tests, the software re-allocates all available memory as blocks of working storage. Then the routine performs an integrity check on the working storage to verify that it is accessible.

When the version string mismatch test passes, the firmware begins the printhead dot resistance test.

Printhead Dot Resistance

The printhead resistance routine is a hardware test of all 832 individual dots for correct resistance value. If the test passes, the printer switches to online ready mode. If the test detects any dots that are open or have high resistance (>852 Ohms), error #765 appears on the LCD. Failure does not halt printer operations.

TEST LABEL (LEVEL 1)

Test Label can be performed in Normal or Diagnostics Test mode. When the printer finishes printing the two test labels, it returns to the ready state.

NV RAM ByteTest

The Non-Volatile RAM test checks the first two bytes of NVRAM. If the test passes, the next test begins. If the test fails, error #909 appears on the display.

Version String Mismatch

The version string test compares the software version in ROM to the version in RAM. If the versions match, the current software is in RAM and the software clears storage RAM. Then the software clears the working storage routine. If the versions in ROM and RAM do not match, error #911 appears on the LCD.

MATERIALS REQUIRED:

Installed supply stock, at least 1” wide X 2” long.

1.If the printer is in Normal Mode, press Feed + Pause at the same time. If the printer is in Diagnostics Test mode, press Feed.

Two test labels print (See Figure 4-3). If the test fails, an error appears on the LCD. Press Clear to reset the printer.

2.Examine the test labels for smearing, image washout, print uniformity, contrast, missing dots, or out of specification readings.

System Restart Condition

The three conditions that cause a system restart are:
