TP 25 IME Test Print

This test print isolates the IME from other system issues. The image is a simple pattern of
coloured bars as shown in

Figure 1

. The image includes primary colour bars printed by all four

print heads. Image size is the width and length of the media less the 4.3 mm (0.017 inch) mar-
gins. The tray selection is from tray 1 or 2 and prints on A4 or 8.5 x 11 inch media only.

Figure 1 IME Test Print

The print is produced simplex with a 600 x 600 resolution. Print orientation (LEF vs. SEF) is
determined by how the selected tray is loaded. The tray is selected automatically based upon
the same priority system used to select a chase source. An error is noted if none of the trays
contain valid media. If a finisher is installed, the sheet is sent to the catch tray on the finisher.

•

The front and rear LED’s give the same information.

•

There is a 7-segment LED display unit on the rear of the machine attached to the SBC
PWB. The LED display should show just a pulsing decimal point when IME test print is
being produced. Refer to

Procedure

Check that either A4 or 8.5 x 11 inch size media is loaded in tray 1 or tray 2. Also check that ink
and the other printing prerequisites are met. Print the IME test print using these steps:

NOTE: All test prints should be printed on A4 or 8.5 x 11 inch plain paper. Use the best quality
media available. Do not use hole punched paper.

Turn the machine off,

GP 14

Open the mid left door,

PL 70.30 Item 16

Remove the waste tray.

Insert an interlock cheater in the front door interlock.

Turn the machine on,

GP 14

During power-up, the IME checks for the combination of waste tray and left side door sen-
sors that activates the test print mode. PEST does not run in this mode.

The red IME error LED begins a repeating series of three blinks with a slight pause
between (111, 111, 111). This sequence indicates IME test print mode is detected.

Close the left side door and install the waste tray. The red IME Error LED turns off and the
green IME OK LED begins a sequence of three blinks. This indicates the IME is in test
print mode. The IME generates the print as soon as the thermals come up to temperature
and any errors are resolved.

NOTE: The red IME Error LEDs blink an error code if the IME determines it is unable to con-
tinue (e.g. out of media or ink). After printing the IME test page, the machine reboots to cus-
tomer mode.

Errors and status are reported by blinking the status LED’s (IME OK and IME Error LED).

•

In the absence of a fault the green IME OK LED flashes in groups of three to indicate nor-
mal test print mode.

•

During normal test print mode, the red IME error LED is turned Off.

•

When an error is detected, the red IME error LED flashes an error code and the green
IME OK LED remains Off.

For example, an error code of 124 is indicated on the red IME error LED by one flash followed
by a brief pause, followed by two flashes and another brief pause, followed by four flashes fol-
lowed by a longer pause. Between each sequence, the LED flutters to indicate the sequence is
repeating.

Three results may occur:

•

111 indicates to close the door and replace the waste tray to proceed with the test print.
The close cover result is flashed to indicate test print mode is detected. Replace the
waste tray and close the left side door. When these actions are completed, the IME Error
LED turns Off, and the IME OK LED flashes the three short flashes followed by a pause.
