5.2 Correcting Simple Problems

Check the condition of the data cable. Replace it if necessary.

Examine the features set-up for a communications mismatch. Do the

features match those of the host computer?

Check data ﬂow with the Data indicator.

• Carriage moves, but there is no printout during Printing Self-test.

Make sure that the ribbon is installed.

Examine the ribbon path. Does the ribbon pass in front of the whole

printhead? Adjust the ribbon if necessary. (See Section 1.3.3).

• Pinfeed paper does not advance.

Make sure that pinfeed paper is depressing the switch on the left

tractor. See Chapter 3.

Push the paper selection lever towards the back of the printer for

tractor feed.

• Single sheet paper does not advance.

Pull the paper selection lever towards the front of the printer for

friction feed.

• Paper not detected by printer even though it is loaded.

Check that the paper falls in front of the triangle marked on the plastic

guide.

5.2.3 Operation-related Problems

• Power/Ready indicator is ﬂashing; Fault indicator is On.

This is an "out of paper" response. Make sure that the tractor/friction

feed lever is in the position needed by your application. Load paper;

the Fault indicator will turn Off, and the Power/Ready indicator will

either turn On or ﬂash. If it ﬂashes, press the Ready switch to turn On

the Power/Ready indicator.

• The LA310 MultiPrinter stops printing; Fault indicator is On.

This is an "out of paper" response. Load paper; if the Ready indicator

is ﬂashing, press the Ready switch. The LA310 MultiPrinter should

resume printing.

Make sure that the paper is not torn or otherwise damaged.
