SPECIAL FEATURES

Some of this copier’s features can be adjusted by your service representative to suit your application needs. This section gives a brief description of these features. If you wish to get more information or use the following features, contact your service representative.

Energy Saver Function

With this function, all input modes are reset and the copier uses less electricity. If you select this function, the copier can automatically turn the energy saver function on at the same time the automatic reset is turned on. Also, you can select one of four levels for the saving ratio. The greater the saving ratio, the more time the copier will need to return to the ready condition.

Automatic Reset Time

1 minute after the final copy is made, all input modes are reset to default modes. If a 1 minute reset time is not appropriate, 3 minutes or no automatic reset can be selected.

Copy Counter UP/DOWN

The copy counter can be set to show the number of copies made (count up) or the number of copies remaining to be made (count down).

Auto Image Density Priority

Auto Image Density mode is selected when the main switch is turned on, or after auto reset. However, a service representative can select the Manual Image Density mode as the standard mode.

SPECIAL FEATURES

Auto Image Density Level

The auto image density level can be made lighter or darker.

Maximum Copy Quantity

The maximum copy quantity can be set from 1 to 99. (99 is the standard setting.)

Reduction/Enlargement Ratio Priority

With the default setting, the reduction ratios are selected at first when pressing the Reduce/Enlarge key. (Ex.: A4 version machine: 93% → 82% → 71% → 141% → 121%. See page 12.) You can cancel this setting and give priority to the enlargement ratios.

Optional Key Counter

To use the key counter, additional service parts are required. Please contact your service representative.

TROUBLESHOOTING Clearing Misfeeds

TROUBLESHOOTING

Clearing Misfeeds

When there is a paper misfeed, a misfeed location number (PE, J0, J1, or J2 ) is displayed in the copy counter. If J0, J1 or J2 is displayed, the Check Paper

Path ( ) indicator will also light. Remove misfed paper as follows.

PE: See page 25. J1: See page 27.

*Illustration shows type 2.

J2: See page 28. J0: See page 31.

Do not leave any torn scraps of paper within the copier.

After removing the misfed paper, make sure that all units are returned to their original positions and the top unit and front cover are closed.

When a paper misfeed occurs, the copier keeps track of the selected copy modes and how many originals have been completed. It is not necessary to reset the copy modes and the copy quantity after removing misfed paper.

Repeat the procedures described in this section until the Check Paper Path indicator and misfeed location number (PE, J0, J1, or J2) go out. (The indicators do not function unless the front cover is closed.)

Do not open the front cover after the misfeed condition is cleared. (The copier’s memory will be erased if you do.)

If you have a document feeder, make sure to use the top unit stand to keep the top unit open.
