■ Auto Paper Selection

The width is detected by the position of the tractor set to the width of continuous paper. The length in feeding direction is detected by the number of holes per page entered on the copier’s control panel. Both dimensions are used to identify the size of the original, thereby enabling automatic selection of cop y paper .

If ‘width of original/lengthwise dimension’> 1, A4 (LTR) is selected. If ‘width of original/lengthwise dimension’< 1, A4R (LTRR) is selected.

■ Auto Paper Selection

Study the table below for samples of identification:

■ Feeding Originals

When the Copy Start key is pressed, the first six pages are fed at longer intervals than usual, allowing the user to fold the continuous paper into pages.Thereafter, the pages are fed continuously up to the last page.

■ Delivered Copies

If 250 or more copies are to be made, copying operation will stop at the 250th copy and the copier will indicate a message asking the user to remove the copies from the copier’s copy tray or the sorter’s nonsort bin. Copying operation will resume at a press on the Copy Start key.

3. After Making Copies

1) Remove the continuous paper (original) from the original delivery tray; shift down the sub guide, and put in the original delivery tray.

2) Press the C.F.F. releasing button, and put the C.F.F. back into its original position; then, close the copyboard cover.

Figure 1-18

Check to make sure that the tray is put in before putting the C.F.F. back into its original position. (Be sure that the C.F.F. is securely back in position; otherwise, the copier may not operate.)

E. Energy Saver Mode and

Auto Power-Off

1. Energy Saver Mode

When the Energy Saver key is pressed during standby, the copier will enter energy saver mode, turning off all indications on the control panel except the Power indicator and the Energy Saver indicator. q In energy saver mode, keys other than the

Energy Saver key will not be accepted. w During energy saver mode, the fixing tempera-

ture is controlled to a temperature lower than

usual. (This may be changed in user mode.) e Energy saver mode may be de-selected by

pressing the Energy Saver key once again.

2. Auto Power-Off

The copier’s power switch will turn OFF if the copier is left alone for a specific period of time (auto power-off). q The copier will be in auto power-off state if it is

left alone for about one hour after the last key

operation. (The time may be changed in user

mode.) w The fixing assembly will turn OFF when auto

power-off starts. e To end auto power-off, turn ON the power

switch.

When auto power-off state is ended, the copi-

er will remain in wait state until the tempera-

ture of the fixing assembly reaches a specific

value.(You may select auto start at this time.)

F. Margin Mode

You can use the Margin key to create a margin along the left/right or the top/bottom of copies for binding.

Reference:

In this mode, the image of the original is

shifted left/right or top/bottom, thereby cre-

ating a margin on the left/right or the

top/bottom of copies.

q The margin may be between 1 and 20 mm in

1mm increments.

G. Frame Erasing

1. Original Frame Erasing

You can use the Original Frame Erase key to erase the frame-like image of an original on a copy.

In this mode, a margin is created along the copies corresponding to a width of about 2 mm on the original.

Figure 1-20

2. Sheet Frame Erasing

You can use the Sheet Frame Erase key to erase a frame-like image on copies.

In this mode, a width of about 7 mm is created along the sides of the copies.

3. Binding Erasing

You can use the Binding Erase key to erase

the image of holes punched in the original.

In this mode, a width of about 18 mm (may be varied between 1 and 20 mm) is created along the trailing edge of copies.

Figure 1-22

4. Book Frame Erasing

You can use the Book Frame Erase key to create a width of 2 mm on copies in relation to the original; 2 mm wide along the sides, and 20 mm wide along the center.(The width along the center may be varied between 5 and 40 mm in 1mm increments.)

Figure 1-23

H. Making T wo-Sided Copies

You can use the Two-Sided Copy key to make

the following types of copies:

• from one-sided original to two-sided copy

• from two-sided original to two-sided copy

• from two-sided original to one-sided copy

I. Making Overlay Copies

You can use the Overlay Copy ke y to mak e the

following types of copies:

• overlay copy

• page separation overlay copy

J. Auto Paper Selection

When this mode is selected, the copier will automatically select the tray that contains paper of the size most suited to the selected original size and the reproduction ratio.

If no such paper is available, the copier will select the cassette containing paper which can accommodate the most image and will indicate the selection on the touch panel display.

Press the Copy Start key to resume copying;to stop copying, press the Stop key.

Paper, if any, set in the multifeeder is con-

sidered for auto paper selection.

K. Auto Zoom

When this mode is selected, the copier will select an appropriate reproduction ratio to suit the selected original size and copy size.

All originals, however, will be identified as being one of the default size originals so that the copies will be of a ratio falling within the range of default ratios.

You cannot combine auto Zoom with auto

paper selection.

L. Interrupting Ongoing

Copying Operation

You can interrupt continuous copying to make

copies of a different original.

1) Press the Interrupt key to select interrupt mode.

q You can make as may as 999 copies. w You cannot use auto paper selection. e You may use the RDF for manual feeding. r You cannot use this mode if you are using

the C.F.F.

2) To de-select interrupt mode, press the Interrupt key once again.

M. Using Cover/Sheet Insertion

Mode

When using the RDF, you may take advantage

of this mode for the following:

cover: to add a front over. back cover: to add a back cover. inserted sheet: to insert sheets between pages. Moreover, you can copy originals on the front

cover, back cover, and inser ted sheets while taking advantage of various copying modes (twosided copying, for example).

However, no more than 20 sheets may be

inserted.

N. Transparency Interleaving

Mode

Use transparency mode when copying on

transparencies continuously with originals in the RDF so that interleaves (plain paper) will automatically be inserted between transparencies during delivery for protection. (You may copy images on the interleaves.)

O. Image Composition Mode

In this mode, two or four originals are reduced

and copied on a single sheet of copy paper.

This mode may be any of the following four

types:

• 2-on-1 mode

• 4-on-1 mode

• 2-on-1 two-sided mode

• 2-on-1 overlay mode

P. Diffrent Size Original Mode

Use this mode when making copies by stacking originals of different sizes in the RDF. In this mode, you can take advantage of auto paper selection and auto zoom for each different original. (Copying will be slower, however, since the copier has to identify the size of each original.)

The originals to be stacked in the RDF must be of the same configuration, i.e., as in the case of A4 and A3, they must have the same feeding direction size.

Q. Photo Mode

In photo mode, the copier varies the intensity of the scanning lamp and the output of the charging assembly to reproduce images of photos.

R. Mode Memory

As many as 12 modes may be stored in memory.

1) Set the appropriate mode settings.

2) Start extension mode, and select ‘mode memory’.

3) Press the Store key.

4) Press the appropriate Copy Mode Memory key

(M1 through M12).

5) Press the key.

q The settings will be stored. (A press on the

Copy Mode Memory key will recall the settings.)

w The settings will remain when you press

the Reset key or when you turn OFF the power switch.

e The settings will be cleared when you enter

new settings for the same key.
