Serial Loop Back Test

This test evaluates serial port circuits on the Control Board Assembly (nothing external to the Control Board), so communication setting DIPs 1 through 10 do not affect this test.

TOOLS REQUIRED:

Loop Back Plug 114271

1.Turn printer off and disconnect host serial port connector from CN 7.

2.Install Loop Back Plug into RS-232 Serial Port CN 7. See Figure 4-4 for plug wiring.

3.Turn the printer on and go into Diagnostics Test Mode 2 (002). This is accomplished by pressing the Feed or Clear key from Mode 1 (001).

4.Press PAUSE.

5.The test runs automatically once initiated, and takes approximately two seconds.

6.If the test passes, 222 is displayed. If the test fails (Loopback Plug not installed, installed incorrectly, or bad Control Board Assy. components) error #499 is displayed.

7.Press Feed and Clear to exit.

Parallel Port Test

The parallel port timeout test can be used with version

3.1or greater firmware. When the parallel port is in flow control, the printer continues to accept data one character at a time until the entire receive buffer is full. The rate that data is accepted can be set through this diagnostic mode. The default is one character per every 10 seconds. This value prints out on the test label.

To change the parallel port timeout:

1.Set lower DIP switch 3 to ON. The display reads 000.

2.Press Feed and Clear at the same time until the display reads 003 (Mode 3).

3.Press Pause to enter the parallel port timeout mode.

4.Press Clear to increase the timeout and press Feed to decrease the timeout.

The display changes to show the amount of the timeout.

5.Press Feed and Clear at the same time to exit data dump mode. The display reads 000.

The amount of data the application processes from the communication driver is 128 bytes at a time. Flow control is now activated when there is 512 bytes left available in the buffer and flow control is now deactivated when there is 1024 bytes available in the receive queue.

Diagnostics Test Mode

There are two types of Diagnostics Tests; those performed off-line by pressing some keys and those performed using SENDFILE. Table 4-1 lists the tests and procedures that can be performed in Diagnostics Test mode.

Performing a Virgin Printer Reset

A Virgin Printer Reset sets the printer to its original factory settings and erases all data in RAM. To initiate a virgin reset, hold down Feed + Clear + Pause for approximately two seconds, and release.

NOTE: Using “Virgin Reset Command“ in SENDFILE requires the Service Password.

Printing a Test Label

Print a test label by pressing the Feed while in Data Dump mode or Diagnostics Test mode. For more information on printing a test label, see “Test Label,” earlier in this chapter.
