C. Test Print
Test printing takes either of two forms: engine test printing or controller test printing. If a fault
occurs in the Printer, make a test print to identify the symptom.
1 . Engine test printing
The Printer has a pattern consisting of horizontal lines (at intervals of about 0.6 mm). The Test
Print switch is found at the rear of the Printer (Figure 1-4-2). After making sure that the photosen-
sitive drum is at rest and the Printer is in standby state, press the switch once to generate a single
test pattern. Hold down the switch to generate test patterns in sequence.
A source of paper may be selected for test printing. If the selected source is without paper, the
internal cassette will be used.
