Notes on using the test generator

If the display is not functioning

■

Both

POWER

and

SELECT

indicators should be on, indicating the ready

state.

■

When using the generator for enabling or disabling the startup page,

the

SELECT

indicator blinks for 45 seconds, then stays on.

If the display is functioning

■

When using the generator for enabling or disabling the startup page,

the

SELECT

indicator blinks for 45 seconds, then stays on. During this

45 second period, the display alternates between

processing data

and

parallel

, then it indicates

Note

Do not use the test generator for making test prints. Use it only for

enabling and disabling the startup page.

Entering Factory Mode

Turn the printer off and unplug the power cord.

Hold down the front panel

POWER

button and right (

⇒

) arrow key at

the same time.

While holding down the

POWER

button and right (

Troubleshooting in Factory Mode

Selecting tests

In Factory Mode, you can choose from 32 tests. You can only run one test each

time you enter Factory Mode. To leave Factory Mode without executing any

test, press the

POWER

button to turn off the printer.

There is no visual indication of what test has been selected. Each time you press

a key or button to step through the tests, the printer produces an audible tone;

count the tones to determine what test you are on.

Press the right arrow key to step through the tests. To step back

through the tests, press the

POWER

button while holding down the

right (

⇒

) arrow key.

Count the tones to determine what test you are on; press the

POWER

button to select the test. The printer produces a different audible tone

to conﬁrm the selection.

If the test has a sub-menu, press the

POWER

button to enter the

sub-menu. Press the right (

⇒

) arrow key to step through the

sub-menu items. Again, the printer produces audible tones as you

step through each test; count the tones to determine what test you

are on. Press the

POWER

button to enter the sub-menu test.

same patterns as for test number 6, but in

number 6 they are printed immediately upon

entering the test. In this test, you must select

a test from the sub-menu to get a print.
