2.2 Operation Precautions

Operating environment

The environmental requirements for correct operation of the copier are as follows.

Temperature: 10°C to 30°C with fluctuations of no more than 10°C

within an hour

Humidity: 10% to 80% with fluctuations of no more than 20% within an

hour

Acoustic noise

Machine Noise Regulation 3 GSGV, 18.01.1991 : The sound pressure level at the operator position according to EN 27779 is equal to or less than 70dB(A).

Proper use

To ensure the optimum performance of the copier, follow the precautions listed below.

Never place heavy objects on the original glass or subject it to shocks.

Never open any copier doors or turn off the copier while it is making copies; otherwise, a paper jam will occur.

Never bring any magnetized object or use flammable sprays or liquids near the copier.

Always make sure that the power plug is completely plugged into the

✚

electrical outlet.

Always make sure that the copier’s power plug is visible and not hidden by the copier.

Always unplug the copier from the electrical outlet if the unit is not to

✚

be used for a long period of time.

Always provide good ventilation when making a large number of con-

✚

tinuous copies.

CAUTION

A negligible amount of ozone is generated during normal operation of this copier. An unpleasant odor may, however, be detected in poorly ventilated rooms during extensive copier operations.

For a comfortable operating environment, it is recommended that the

➜

room be well ventilated.

Konica 7915/7920 2-3

Page 28

Precautions

CAUTION

If the ventilation duct at the top of the copier becomes blocked, the inside of the copier will accumulate heat, resulting in a malfunction or fire.

Do not place any objects over the ventilation duct.

➜

CAUTION

The area around the fusing unit is extremely hot.

Be careful not to touch any parts around the fusing unit, other than

➜

those indicated in this manual, in order to reduce the risk of burns. Be especially careful not to touch parts marked with warning labels, and their surrounding areas.

If you get burnt, immediately cool the skin under cold water, and then

➜

seek professional medical advice.

Transporting the copier

If you need to transport the copier over a long distance, consult your service representative.

Care of copier supplies

Use the following precautions when handling the copier supplies (toner, paper, etc.).

Store the supplies in a location that meets the following requirements:

✚

free from direct sunlight away from any heating apparatus not subjected to high humidity not extremely dusty

Store in a sealed plastic bag in a cool, dark place paper that has been

✚

removed from its wrapper but not loaded into the copier.

Only use toner that has been manufactured specifically for this copier. Never use other types of toner.

Keep all supplies out of the reach of children.

2-4 Konica 7915/7920

Page 29

Precautions

CAUTION

Precautions for handling toner:

➜

Storage of copies

✚

Be careful not to spill toner inside the copier or get toner on your clothes or hands.

If your hands become soiled with toner, immediately wash them with soap and water.

If toner gets in your eyes, immediately flush them with water, and then seek professional medical advice.

Copies that are to be kept for a long time should be kept where they are not exposed to light in order to prevent them from fading.

Copies pasted together using adhesive that contains solvent (e.g., spray glue) may dissolve the toner on the copies.

Color copies have a thicker layer of toner than normal black-and-white copies. Therefore, when a color copy is folded, the toner at the fold may peel off.

The Interrupt mode is also cancelled when the copier automatically resets itself 1 minute after the last key is pressed (“Auto Panel Reset” parameter). However, the Interrupt mode is not cancelled if a copy job is still interrupted. The length of time until the copier automatically resets itself can be set between 1 and 9 minutes. The “Auto Panel Reset” parameter can even be turned off. By turning off the “Auto Panel Reset” parameter, the In- terrupt mode will not be cancelled automatically. For more details, refer to “Specifying Default Settings (“User’s Choice” Function)” on page 8-8 and page 8-15. Some functions cannot be interrupted. In addition, some settings are not available while a copy job is interrupted. For more details, refer to “Function Combination Table” on page 12-10.

✎

Tip

Pressing the [Interrupt] key resets all functions and settings to their defaults and selects the “Non-Sort” setting on the Finishing screen. For more details, refer to “Resetting the Copier (“Default Settings” Function)” on page 8-1. Settings cannot be stored during Interrupt mode. In addition, the “OHP Interleaving” and “Job Recall” functions are not available.

Auto Paper Source Change Feature

If the tray or drawer runs out of paper while copying, the copier will automatically switch to a different paper source and continue copying provided that the new tray or drawer contains paper of the same type and size in the same orientation. If the large-capacity cabinet (DB-431) is also installed, up to 3,250 sheets of “A4C” paper can be fed continuously.

Precautions for Multi-Sheet Feeding and Single-Sheet Feeding

The following types of documents should not be used for multi-sheet feeding or single-sheet feeding, otherwise paper misfeeds or damage to the document may occur. Instead, these types of documents should be fed manually.

Thin documents such as typewriter paper or paraffin paper

Thick documents

Standard size documents larger than A3 or smaller than A5

Precautions for Manual Feeding

The following precautions should be observed when manually feeding the types of documents listed.

For non-standard sized documents:

The document size cannot be detected automatically, therefore, the Paper setting “Auto Paper” and the Zoom setting “Auto Size” cannot be used together. Select a different Paper setting by touching “Paper” on the Basic screen, then selecting the paper size of the document, or select a different Zoom setting by touching [Zoom] on the Basic screen, then selecting a zoom ratio. (Refer to page 6-14 for more details.)

For documents that are transparent or translucent, such as overhead

transparencies or diazo photosensitive paper: Place a blank sheet of paper of the same size as the document over the document. (Refer to page 5-12 for more details.)

For thick objects, such as books:

Scan without closing the original cover or duplexing document feeder. In addition, do not press down extremely hard on the document, otherwise the copier may be damaged. (The original glass can only resist a weight of up to 2 kg.)

5.2 Feeding the Document Through the Duplexing Document Feeder

The duplexing document feeder feeds in, scans, then automatically feeds out each page in a multi-page document, one page at a time. The correct types of documents must be loaded in order for the duplexing document feeder to function properly.

Multi-Sheet Feeding (Sheet Documents)

A stack of documents of different sizes can be copied as a set using the duplexing document feeder. (Refer to “Feeding Documents of Different Sizes (“Mixed Orig Detection” Function)” on page 7-17.)

To make copies using multi-sheet feeding (sheet documents)

A maximum of 50 document pages can be loaded.

When loading the documents:

Be sure to adjust the paper guide to the size of the document, other-
