Trouble-Shooting

Checking Vertical Alignment

In bidirectional printing, characters printed from left to right tend to misalign with
characters printed from right to left as shown below:

This example shows how printing looks

when characters are vertically

misaligned. Note that the left

margin is not straight.

The vertical alignment function corrects the vertical character displacement that sometimes
occurs with bidirectional printing and results in a poor appearance especially in printing
tables. This function is defined as one of the power-on initiated test functions. If you notice
misaligned printing, start this function to check and correct the vertical print alignment.

Make sure that continuous forms paper or single sheet paper is loaded in the printer. If
possible, use forms at least 216 mm (8.5 inches) wide for LA36N or 356 mm (14 inches)
wide for LA36W to avoid printing on the platen. Then proceed as follows:

1. Start the vertical alignment test.

Turn the printer on while pressing the

Protocol

button until the printer beeps. The printer

prints the help menu and then starts printing rows of parallel bars at Letter quality speed.

Note:

Do not press any buttons alone or in combination except for pressing the

Protocol

or the

Set-Up/Quit

button alone when turning the printer on, to avoid

initiating unexpected tests not permitted for the user.

2. Adjust the vertical print alignment at Letter quality speed.

Examine the parallel bars. If the bars are aligned (not jagged), go to step 3. If the bars

are offset, repeatedly press the

button or the

button until the bars are aligned.
