-12-

STEP 9. Put the printer lid on the Printer.

Fig. 15 Printer with Fanfold Paper Set Completely

NOTE: When the MX-80 Type II is to be used on a desk or a bench, arrangement

of the fanfold paper in parallel with the MX-80 Type II as shown below will permit the paper to be folded in an accordion style.

Fig. 16 Example of Paper Arrangement

6.2. Removal of fanfold paper To remove the fanfold paper, follow either of the two methods described below.

(1) To disengage the paper from the paper holding mechanism, pull it forward out

of the Printer.

NOTE: Do not attempt to pull out the paper in the backward direction.

(2) Feed the paper out of the printer by electrical operation. For this, turn the

Power Switch on and push the Line Feed button. (Details are described later.)

-13-

6.3. Column layout on fanfold paper When fanfold paper of from 4” to 10” in width is supplied with the MX-80 Type

I I, the graduations on the scale can be used as the indexes of print column positions

(1 to 80). Alignment of the print start position on fanfold paper with the 1st column position at the extreme left of the scale will facilitate column layout. Accordingly, center the paper by adjusting it to these indexes of the scale.

6.4. Top of form position setting The term “Top of Form position” is defined as the position in which the first print

line lies on the form, and this position is determined when the power switch is turned on. Namely, adjust the paper position by the manual paper feed knob so that the required line position (i.e., the point at which the first line of the form is desired to be printed) is at the print head level. If, at this point, power is applied to the printer, this line position automatically becomes the Top of Form position. When printing forms, the matchmarks located on both the sprockets facilitate the setting of the Top of Form position on the fanfold paper. To set the Top of Form position, first enter (or preprint) a mark at a position on the edge of the paper 77mm above the first print line position of the paper, then align this mark with the matchmarks on the sprockets by turning the manual paper feed knob. At this point, turn the Power Switch on and the Printer will recognize this position as the Top of Form position. Now, the printing can be started from the Top of Form position.

In case of feeding one page of fanfold paper by operating the MX-80 Type II by the input of FF code, the abovementioned adjustment is effective.

-14-

7. Gap Adjustment

The adjustment of a gap between the head nose and the platen is used to adjust the printing pressure as well as to suit paper of a different thickness. (1) Move the head adjusting lever (located on the left frame of the Printer) forward

or backward to adjust the gap between the head nose and the platen. (See

Fig. 18.) Forward: To widen gap. Backward: To narrow gap.

NOTE: With a thick paper, be sure to widen this gap.

(2) Adjust the position of the head adjusting lever according to the type of paper

to be used.

Paper Single-leaf paper Carbon paper sheets

Position of adjusting lever Set the lever to the 4th step. Set the lever to the 7th step.

(3) Should printed characters become faint due to the use of the printer for an

extended period, move the head adjusting lever backward (in the direction) by one step. (See Fig. 18.)

(4) When a set of carbon paper sheets is used, be sure that no characters are

printed within the area two lines each above and below the perforation.

8. Power Connection

The EPSON MX-80 Type II Dot Matrix Printer is capable of operating on the following three types of AC power. (1) 115V AC, 60Hz (2) 220V AC, 50Hz (3) 240V AC, 50Hz Before connecting the MX-80 Type II to a power source, make certain of the

primary AC rating from the label located on the chassis at the rear of the Printer.

After connection of the Printer to the proper power source and upon application of power to the Printer, “Initialization” will take place in the Printer with the

effects described in paragraph 1.4, Appendix 1. If your MX-80 Type II has a

primary AC rating different from the available power source, do not attempt to

operate the Printer. Please obtain a replacement unit with the correct AC rating

from the store where you purchased the MX-80 Type I I.
