1. PAPER FEED TEST

• To check for correct paper passage of the paper feed and transport system by letting the machine consecutively take up and feed paper without involving actual printing action.
• Here are the details of operation involved in the paper passage motion. The scanner does not make any scan motion. Paper is fed until the corresponding paper source runs out of paper. No counters are activated. (Except PM counter, maintenance counter, supplies counter) It cannot be operated at the time of warming up. A printing paper source can select on the screen of the function mode.
• Used when a paper misfeed occurs

Procedure

• Select the paper source. TRAY1/BYPASS
• Pressing the OK key will start the check.
• Press the Stop key to stop the paper feed test.

2 PROCESS CHECK

• HV output (for factory setting only) *Should not be used

3 TCR AUTO ADJUST

1. To make an automatic adjustment of the TCR sensor.
2. Used at setup.
3. Used when developer has been changed.
4. Used when IU has been replaced.

Procedure

NOTE
• Before starting this adjustment, the toner bottle must be removed.

1. Press the OK key to start the adjustment.
2. The adjustment sequence automatically stops as soon as the adjustment is made, and TCR gain value is displayed.
   <Conversion formula of TCR gain value to voltage>
   TCR control voltage (V) =3.3 x 2 x [TCR gain value] / 256

4 PRN TEST PATTERN

PATTERN1

• To produce a test pattern for image adjustments.
• When skew, registration, or zoom ratio has been adjusted.
• Here are the details of operation involved in the paper passage motion. The scanner does not make any scan motion. No counters are activated. (Except PM counter, maintenance counter, supplies counter) It cannot be operated at the time of warming up. A printing paper source can select on the screen of the function mode. The writing to a photo conductor is made as A3 size to every paper. The erasing of circumference of paper is effective. (Leading edge/trailing edge/vertical edge)

Procedure

1. Load the A3 or 11 x 17 paper, and select the paper source.
   NOTE
   • To produce a test pattern, be sure to use the paper of A3 or 11 x 17 sizes. Using paper that is smaller than A3 or 11 x 17 may cause smear on the back side of paper ejected on the output tray. If this problem occurs, feed several sheets of paper through the machine to resolve the problem.
2. Select the type of test pattern.
3. Press the OK key to let the machine produce the test pattern.

PATTERN2

• To produce halftone and gradation test patterns.
• Used when checking for uneven density or uneven pitch.
• Used when checking for gradation reproducibility.
• Here are the details of operation involved in the paper passage motion. The scanner does not make any scan motion. No counters are activated. (Except PM counter, maintenance counter, supplies counter) It cannot be operated at the time of warming up. A printing paper source can select on the screen of the function mode. The writing to a photo conductor is made as A3 size to every paper. The erasing of circumference of paper is effective. (Leading edge/trailing edge/vertical edge)

2. Select the type of test pattern.
3. Press the OK key to let the machine produce the test pattern.
