2. MAJOR UNIT REPLACEMENT

WARNING!

Disconnect the power cord before replacing the main parts.

CAUTION:

1.NEVER separate the ribbon motors from the attaching plate, (bracket) because doing so will change their adjustment. (See Fig. 2-8)

2.NEVER remove the two screws painted red on the side of the print block. (See Fig. 2-13)

3.NEVER remove the four screws on the side of the print block. (See Fig. 2-13)

4.NEVER remove the four screws painted red fixing the right plate and reinforcing plate. (See Fig. 2-16) However, the machine with a serial number of 4Txxxxxx or later is not equipped with the red screws because of the change in the right plate shape.

5.NEVER remove unmentioned screws because doing so will change their adjustment.

1)Turn the power off.

2)Open the top cover to remove the four FL-3x5 screws. Slide the top cover to the left to release the damper and remove the top cover.

3)Remove the seven screws (FL-4x5 and B-4x5) to remove the left side cover.

NOTE: Instructions to remove the top cover and left side cover are omitted from each removal/ installation procedure provided below.

■ Lubrication

CAUTION: 1. Lubrication:	During parts replacement
2. Kinds of oil:	FLOIL G-488: 1kg kan (Part No. 19454906001)

Any machine is generally in its best condition when delivered; therefore, it is necessary to try to keep this condition. Unexpected failure occurs due to lack of oil, debris or dust. To keep its best condition, periodically clean the machine and apply proper kinds of oil to each part in which lubrication is needed. Although the frequency of lubrication varies according to how much the machine is used, at least it is necessary to lubricate before the machine becomes dry. It is also necessary to wipe off excessive oil as it collects dirt.

CAUTION: Do not spray the inside of the printer with lubricants unsuitable oil can damage the mechanism.

4.Install the media guide plate to the printer so there is a 1.5 to 2.5 mm gap between the media guide plate and the printer block base.

2.11 Correcting Skew Printing

•If media still skews after adjusting the pinch roller shaft ass’y with the jig, follow the procedure below to correct the skew problem.

1.Check if the media skews right or left.

2.Loosen the B-4x12 screw to move the pinch roller cover to the front or rear of the printer depending on the skew direction.

Fig. 2-27

When the media skews right, move the pinch roller cover to the front.

When the media skews left, move the pinch roller cover to the rear.

•If a paper skew problem should occur when using rolls wound with labels facing outside after completing the modification, adjust the paper guide as follows.

*In case the label skews to the right side of the print head, move the guide downward.

*In case the label skews to the left side of the print head, move the guide upward.

7.Reassemble the left side cover and the top cover in the reverse order of removal.

8.After reassembly is complete, perform a test print to confirm that the cutter works properly.

After printing a print sample at a speed of 6"/sec., feed the media about 33 mm and check that the swing cutter works without error. After cutting the media, feed the media about 33 mm in the reverse direction and check that it correctly stops at the print start position.

NOTES: 1. If the top edge of label winds onto the platen in cut issue, set DIP SW. 1-5 to ON.

(Refer to the Owner’s Manual)

2.Retain the parts that are removed during installation of the cutter unit. They will be required when the printer is modified to a standard type.

■ Adjusting the Cutter Guide Plates

After replacing the cutter unit the following adjusting procedure should be employed to prevent paper jams.

1.Attach the cutter guide plate A with two SM-4 x 6C screws so that the fixed cutter is positioned 0.1 mm to 0.4 mm above the bottom of the cutter guide plate A.

2.Attach the cutter guide plate B with two FL-4 x 8 screws so that there is a clearance of 0.5 mm between the cutter guide plate A and cutter guide plate B using a clearance gauge.
