1.5.1 Roll paper

1.5.1.1 Adjusting the Roll Paper Guide

1. Adjust paper guide A (1) to the paper width. Paper width: 2.75 inches (69.5 mm) or 3.00 inches (76.2 mm)

1) When the printer is shipped, the paper width is set for wide roll paper (3 inch or 76.2 mm width)

o425_10.jpg

2) To use narrow roll paper (2.73 inch or 69.5 mm width), hold up the roll paper guide and move it to the left to insert

into the hole (1) at the lower frame.

o425_10.jpg

3) The figure below shows the proper guide position for narrow roll paper (2.73 inch or 69.5mm width). (To return the guide to the position for wide roll paper, reverse step 2).

o425_10.jpg

User’s Guide: English 17

2. Adjust paper guide B to the paper width.

1) Pull out the set paper in arrow direction (a) and push it in the arrow direction (b) until it stops or until it touches the inside of the Guide-Rear edge (1).

2) Keeping the paper in position, turn the adjusting screw counter-clockwise to release the paper guide B (2) and adjust it to fit the roll paper edge. After paper width adjustment, turn the screw (3) clockwise to fasten the paper guide B.

OKIPOS 425S

1.5.1.2 Loading the Roll Paper

Use roll paper that matches the specifications.

Note: The printer must be turned on before installing the roll paper.

1. Fold the paper so it is exactly straight and even (1), and will not tear off jaggedly (2).

OP425_01b.eps

2. Turn on the printer and open the printer cover. Remove the rewinder.

3. Insert the roll paper as shown below.

o425_37.jpg

4. Insert the tip of the paper into the paper inlet as far as it will go, and feed the roll paper until the paper comes out from the top of the printer.

o425_100.jpg

User’s Guide: English 19

5. When using the rewinder, follow the steps and the illustration below.

1) Turn the flange into the arrow direction and remove it.

o425_93.jpg

2) Insert the tip of roll paper into the groove of the rewinder as shown in the detail figure. Then, turn the rewinder into the arrow direction to wind the roll paper around it 2 or 3 times.

o425_94.jpg and o425_95.jpg

3) Insert the flange into the rewinder (to the arrow direction 1) until it stops, then turn it into the arrow direction 2 to

o425_96.jpg

lock.

4) Mount the rewinder on the printer.

Note: When using narrow roll paper (2.73 inch or 69.5 mm width), turn over the flange as the arrow (e) and then

mount it following the above procedures 3) and 4).

Note: The flange can be demounted in the reverse procedures to its mounting.

Note: This printer can use two kinds of roll paper. Their widths are 69.5mm+0.5mm and 76.2mm+0.5mm.

Roll papers other than the above are outside the guarantee, and we recommend these papers not be used. If you use unrecommended roll papers and have problems, we will not guarantee either the printer or the performance. Even roll papers outside the above defined range can be used by inserting the Spacer that comes with the printer, if the space between the Flange and the Roll paper is 1mm. You must test thoroughly before you decide to use it, to make sure that there is no problem.

6. Close the printer cover.

OKIPOS 425S

1.5.1.3 Adjusting the Roll Paper Near End Sensing Position

The paper near end detector detects when the paper is almost gone by measuring the diameter of the Roll paper. If you want to change the amount of paper remaining when the printer stops printing, follow the steps below to adjust the

paper near end detector.

Note: If the inner diameter of the Roll paper core is more than 26mm (1.02 inch), the Roll paper near end detector may

not work properly.

1. Open the printer cover and remove the rewinder. 2 Determine the point on the Roll paper at which you want the near end detector to be triggered. Then measure the distance

A shown in the illustration.

OP425_02.eps

Note: There may be some difference between the measured distance A and the actual sensing position.

3. Find the corresponding adjustment position number from the table below. Distance A Adjustment position number 4 mm (0.16") #1 6 mm (0.24") #2 8 mm (0.32") #3 11 mm (0.43") #4 19 mm (0.75") #5 26 mm (1.02") #6

Note: Above values are applicable when the inside diameter at the core of the Roll paper is 10 mm.

4. Loosen the detector screw with a coin or screwdriver.

5. Set the detector scale to the position you determined from the table by moving the detector screw up or down. The

2.3.3 How to Operate

Start

To start the Menu Mode, turn the printer on while holding down SW2 + SW1. When the printer’s initialization ends correctly, the printer prints the title “Menu Print” and all the menu items and set values. Then, the printer line-feeds until the print result goes beyond the Manual Cutter position, prints the item/set value immediately after “Menu Print,” then waits for a switch to be pressed.

Operation

The switch functions during the menu mode are as follows:

A25008.doc

Switch Function

Advances the set values of the Menu Item, one at a time. From the last set SW2 SW3 Ends Menu Mode.

SW1 Advances the Menu Items, one at a time.

SW4 Feeds the receipt, by one line

value, returns to the first set value.

Registers the set values in EEPROM, then prints the end message “Menu

End” and returns to the same initialized state as at power on.

From the last Menu Item, returns to the first Menu Item.

2.4 Hex Dump Function (Receipt)

This function converts received data, as it is, to character codes, and prints it in the Receipt mode. The printed contents are as follows: Upon receiving one byte, the printer divides it into three characters, High-nibble, Low-nibble and a space. Regarding these as 1 block, the printer prints 8 blocks in one line, then, prints the same data in the character format.

Upon entering the HEX dump mode, the printer prints “Hex Data Dump”. (Title printing)

. . . .

Hex dataLine No. ASCII data

2.4.2 How to Print

1 If it does not receive data after 150ms have passed since receiving last data, the printer starts printing (CR) if it has some

data. (If there is not enough data to form 8 blocks, spaces will be used.) If it subsequently receives data, the printer prints from a position next to the position at which the printing started.

2 If it receives the I-PRIME signal (Parallel model)/Reset signal (Serial model), the printer starts printing if it has some data,

then feeds one line. Then, the printer is initialized. (If it does not have any data, the printer feeds one line and then is initialized.) After the initialization, the printer starts up in dump mode again and prints. The line number is reset, however, and counting begins from “0000”.

* When I-PRIME signal (Parallel model)/Reset signal (Serial model) is hard reset (setting by Short Plug with Parallel I/F

board and by DIP SW with Serial I/F board), it immediately starts initialization and does not continue hex dump. 3 One line-feed is added for every 16 lines. 4 The count begins from “0000” when the line number exceeds “FFF8.”

2.5 Using the MICR Reader (Option)

If your printer has the factory installed optional MICR (Magnetic Ink Character Recognition) reader that enables the printer to read and process MICR characters on personal checks, read this section.

Note 1: If Cut-sheet Paper or Sprocket Paper has been loaded, eject it before you use the MICR feature. This does not apply

to the Roll Paper.

Note 2: When the Tractor (Option) (1) has been installed, remove or park the Sprocket Paper, then switch the Lever to the

Cut Sheet side (1) from the Sprocket side (3)

o425_52.jpg

Note 3: When using a MICR-version machine, align the marks “䊱” and “䊲” as shown and set the paper along the paper

guide (1).

Note 4: Use a flat Check Sheet. If you use Check Sheets that are dog-eared, have wrinkles, or are wavy, they are more likely

to cause a paper jam, scan failure, or damage to the MICR Head.

o425_59.jpg

User’s Guide: English 39

How to use the MICR Reader

1. Send the command “FS a 0 n” from the host computer. Then the printer shifts to the MICR Mode and waits for the Check

Sheet to be inserted. LED3 blinks slowly in orange (repeats 1 sec ON, 1 sec OFF).

2. Insert the Check Sheet with its magnetic ink print surface up and the magnetic ink print area to the right side of the

direction of insertion, butting it against the right side of the printer. The printer feeds the Check Sheet and reads at the same time.

3. To print on the Check Sheet, send the command “FS a 1” which feeds the Check Sheet to the print start position, then send

the print command.

4. To eject the Check Sheet, send the command “FS a 2.”

5. To have the Check Sheet read results sent again, send the command “FS b.”

5.7.5.1.7 Provisions on Fold, Bend and Curl on Cut-sheet Paper

Paper is apt to sustain bends, cambers or curls resulting from manual handling, carrying, stacking, storing conditions, etc. Therefore, before printing, check and adjust paper in accordance with the provisions below to eliminate paper feed problems.

Do not use paper that does not meet the specifications outlined here: it may cause paper feed problems. Problems caused by using non-specified paper are not covered under warranty.

1) Fold (a) Do not use a sheet which is folded across its width (A). Even if such paper is smoothed, its strength is still uneven. (b) For paper with a folded corner (B), if the fold height after adjustment is 2 mm or less, it may be used for printing.

OP425_17.eps

1 15mm or more 2 Adjusted to make the height 2mm or less

2) Bend and Curl (a) If a sheet has a curl height of 2 mm or less (A), it may be used for manual feed printing. (b) If a sheet has a bending height of 2 mm or more within 15 mm from the bending line (B), do not use it for printing.

5.7.5.3.4 Fixing Method of Multi-part Paper Joint

The joint fixing method for a multi-part paper shall be spot-pasting, line-pasting or crimping. Spot pasting is the proper precaution against position deviation made when piling sheet tiers.

Crimping may cause position deviation of approx 3 mm. Metal staples must not be used. 1 Spot Pasting

a Spot pasting must be conducted on both right/left sides. Paper which is pasted on only one side is not accepted. b Equal amount paste shall be applied to the fixing points, whose size shall be f3 ~f5 mm.

Press the pasting points to prevent lifting.

Be careful not to generate distinct wrinkles. c See the fig. below for the pasting positions. d Apply spot pasting in zigzag alternately for each sheet.

OP425_21.eps

1 Pasting spot 2 50.8mm (2 inch)

2 Line Pasting

a Paste shall be applied evenly to the fixing line, whose width shall be 1 – 2 mm.

Press the pasting line to prevent lifting.

Be careful not to generate distinct wrinkles. b Do not let paste leak out paper edges.

3 Crimping

a Crimp paper on both right/left sides. b Apply crimping from the front surface, making no protrusion on the surface. c All the sheets must be engaged securely with each other at the crimp position free of lifting. d Use a double-type crimp and apply crimping in the direction to produce the crimped mark horizontal to the paper

right/left edges.

e Press paper after crimping to eliminate lifting.

1 Horizontal perforated line 2 Within 1mm

5.7.5.3.6 Position Deviation of Sprocket Holes

Deviation of the sprocket hole positions may be caused when each copy or tier is piled to produce multi-part paper. Use multi-part paper whose sprocket deviation is 0.4 mm or less.

5.7.5.3.7 Binding Holes

Do not use a paper with punched holes. It may invalidate your warranty. If you choose to use punched paper, be sure to test it thoroughly. Follow these guidelines:

1 Do not print within 5 mm of the hole center. 2 Make sure that paper dust is not left on the paper. 3 If a hole passes over the paper sensor, a false paper end signal may result. 4 Make sure that the edges of holes are even with the paper surface. If they stick up, the printhead may not move

smoothly.

5 The positions of holes should be as illustrated in the figure below.

5.7.5.3.8 Corner Cut

Do not use paper with corner cuts. It may invalidate your warranty. If you choose to use corner cut paper, be sure to test it thoroughly. Follow these guidelines:

1 Do not print within the shaded area adjoining a corner cut. 2 Make sure that paper dust is not left on the paper. 3 The perforation of the vertical/horizontal perforated line must not intersect with the corner cut to prevent the paper

from peeling off. (The crossing position of the corner cut outline and the perforated line should be uncut.)

The carriage may be clogged with peeled-off paper. 4 If a corner cut passes over the paper sensor, a false Paper End signal may result. 5 The positions of corner cuts should be as given in the fig. below.

5.7.5.3.9 Wrinkle, Pleat and Swell

Use paper, which has been folded zigzag on horizontal perforated lines, free of wrinkles and pleats. Newly unpacked paper often has wrinkles or pleats on the first and last pages. Please eliminate pages having wrinkles and

pleats before printing. Do not utilize paper whose folding position inflates as illustrated in the fig below, because it may cause malfunction in paper

feed.
