Functions

1.4.4.1 Usual operation

Changes the front and rear paper path alternately.

■ Normal paper is set and the pull tractor is not used:

The printer feeds the paper to the tear off position and cut the paper by the cutter, and feeds backward to paper park position. If the cutter is not used, it goes incomplete changing paper error. So cut the paper at the top of paper and push Pause switch or Front/Rear switch, and the printer feeds the paper backward. After the paper is out, the printer loads the paper from another path's tractor.

■ Overlapping multi-part forms or continuous forms with labels is set or pull tractor is used:

Incomplete changing paper error is occurred immediately. Cut the bottom of paper at current page and push Pause switch or Front/Rear switch, and the printer feeds the paper forward. After the paper is out, the printer loads the paper from another path's tractor.

This switch alternates printer activity between printing and non-printing.

Hold this switch down over 3 seconds, and the printer resets all data.

Push this switch when incomplete changing paper is occurred, then go to the next step.

Adjusts the paper position including "Top of Form" and "Tear off" positions. The ! switch advances the paper forward by 1/216-inch step, and i switch advances the paper backwards by 1/216-inch step.

Pressing it loads continuous paper when the printer is out of paper.

Pressing it shortly executes line feed.

Holding it down for a few seconds executes form feed.

Advances the paper so that the characters' base line can be adjusted at the mark of ribbon mask holder, and enters the "Top of form adjustment" mode. The "Top of Form" LED turns on and the TOF position is adjustable with the "Micro Feed" switches in this mode.

When the "Top of Form" switch is pressed again, this mode is terminated. The adjustment position is stored as TOF, and the paper is fed back to the position before this mode.

When TOF adjustment is executed just after loading, the adjusted position will be treated as the loading position.

This switch is only available when the cover opens.

Advances the paper until its perforation comes to the paper cutting part of the printer cover, and enters the tear off mode. The "Tear off" LED turns on and the Tear off position is adjustable with the "Micro Feed" switches in this mode.

When the "Tear Off" switch is pressed again, this mode is terminated. The adjustment position is stored as the tear off position, and the paper is feed back to the position before this mode. This mode is terminated also by the data arrival from host computers.

Pressing it select copy mode or normal mode.

Pressing it selects one of following pitches; 10 cpi, 12 cpi, 15 cpi, 17 cpi, 20 cpi and PS (proportional spacing).

Pressing it selects one of following fonts. Super Draft, Draft, Roman, Sans serif

Pressing it selects one of the following paper Numbers. 1,2,3,4,5,6,7,8 : When the printer has the paper information. 0 : Always a, b : When the printer has the paper memory data.

■ Normal paper is set and the pull tractor is not used:

The printer feeds the paper to the tear off position and cut the paper by the cutter, and feeds it backward to the paper park position. If the cutter is not used, it goes incomplete changing paper error. So cut at the top of paper and push Pause switch, then the printer feeds backward. After the paper is put, the printer loads selected paper. If incomplete changing paper error is occurred, set the selected paper and push Pause switch.

■ Overlapping multi-part forms or continuous forms with labels is set, or pull tractor is used:

Incomplete changing paper error is occurred immediately. Cut the bottom of paper at current page and push Pause switch, then the printer feeds the paper forward. After the paper is out, the printer loads the selected paper. If incomplete changing paper error is occurred, set the selected paper and push Pause switch.

The printer feeds the paper forward. If the printer can't aware out of paper status, it goes incomplete changing paper path error.

If incomplete changing paper path error is occurred, please cut at the bottom of paper and push Pause switch, then the printer ejects the paper forward.

The printer feeds the paper to the tear-off position and cut the paper by cutter and feeds backward to paper park position. If cutter is not used or the printer fails to feed the paper to paper park position, it goes incomplete changing paper path error.

If incomplete changing paper path error is occurred at the tear off position, please cut at the top of paper and push Pause switch, then the printer feeds the paper backward.

1.4.4.2 Operation at Power On

Prints the self test pattern. To cancel it, make printer pause and turn off the power.

□ DIP switch setting print:

Starts the setting printing mode.

Starts the data dump mode, in which all the input data are printed as hexadecimal numbers and corresponding characters.

Resets the printer to the standard factory setting, except mechanism data area. (i.e. This function is for emergency.)

Resets the printer to the standard factory setting, only mechanism data area. (i.e. This function is for emergency and service.)

□ Clear Driving Line count for ribbon change timing:

Resets the printer to the standard factory setting, only driving line count for ribbon change timing.

□ Paper memory setting:

This makes it possible to print properly on the forms which contain two areas having different thickness in a form and paper type.

□ Mechanism adjustment:

Starts the mechanism parameter adjustment mode. You can adjust Beta parameter, flight time parameter, and Bi-D parameter through this mode.

□ Platen gap adjustment:

Starts the platen gap parameter adjustment mode. You can input Alpha parameter and adjust Beta parameters through this mode.

□ Measurement seeking:

Starts the measurement seeking automatically The carriage stopping length is measured and saved in the EEPROM.

1.4.4.3 Built-in Detection

□ Cover open detection:

When the cover is opened, the printer stops printing and enters the pause mode automatically after several beeps. The printer stays at the state until the cover is closed and the "Pause" switch is pressed. Several printer settings loaded at each power-on can be changed in this operation.

□ Paper width detection:

The printer detects the right paper edge and determines the right end of printable area. The print patterns which exceed that end won't be printed.

□ Automatic paper thickness adjustment:

This printer measures the paper thickness after every paper loading. The distance between print head and the platen is automatically adjusted for proper printing according to the paper thickness.

This function is used to print on a multi-part form with the binding which scratches the print head during paper feeding.

If this function is used, the print head parks apart from those bindings during paper feeding to avoid paper jam. This function can be selected by DIP switch and the through-put will be reduced at that time.

The printer cuts the paper at the perforation position automatically while data is printing.

This function is valid when the perforation cutter is used, selected by DIP SW 3-7, and the paper length is more than 4-inch. The setting of the printer driver has priority over DIP SW 3-7.

Do not use this mode for labels, continuous forms with labels, and overlapping multi-part forms.

□ Automatic TOF position setting:

When TOF position is different from loading position with the printer power on, the printer feeds the paper to the next TOF position automatically.

1.4.5 Paper Memory Function

You can get better printing quality when you print on overlapping multi-part forms or on continuous forms with labels by using the paper memory function.

When you use this function, you have to write the information of paper thickness to the printer using DIP

switches and the control panel in advance.

This function is available only with the front paper path.

You can recall paper memories which you have already written some information in advance when you selects paper No. a or No. b by paper select switch. No. a : recall the memory a No. b : recall the memory b

Notes: 1. 1-inch skip perforation area is automatically included for the overlapping multi-part forms.

2. ESC C, ESC (C, ESC (c is valid while the paper memory function is used.

3. ESC N is valid while the paper memory function is used, but if the skip length is less than 1-inch, the setting will be ignored when overlapping multi-part forms is used.

. 4. ESC 0 is invalid while the paper memory function for overlapping multi-part forms is used.

5. The loading position must be adjusted for overlapping multi-part forms at every loading.

6. If paper position doesn't correspond with TOF when turn on the printer, paper is advanced to the top of the next page automatically.

□ How to write the information of a paper except "Continuous forms with labels" :

1) Make sure the printer is turns off.

2) Select the memory you want to write the information (See DIP SW setting.).

3) Select the page length (See DIP SW setting.).

4) Select the paper type (See DIP SW setting.).

5) Turn the printer on while both sides of Paper Select switch are depressed.

6) The printer writes the information in the memory you selected, and beeps.

□ How to write the information of "Continuous forms with labels" :

1) Make sure the printer is turn off.

2) Select the memory you want to write the information (See DIP SW setting.).

3) Select the page length (See DIP SW setting.).

5) Turn the printer on while both sides of Paper Select switch are depressed.

6) Point the label position when you use the paper with a label.

a) Open the printer cover.

b) Move the pointer (Refer to Figure 1-23.) to one of the label's corner.

up / down ...Feed the paper by "Micro Feed" switches right / left ... Move the printing head by manually.

c) Press "Top of Form" switch.

d) Move the pointer to the diagonal corner of the label.

e) Press "Top of Form" switch.

f) Close the printer cover.

7) Confirm the writing sequence was done correctly by beep sounds.

Once or twice: The information are written to the memory a or b correctly. 3 times : The sequence was not correct, and it was ignored.
