and Sprocket Idler with O-rings.
CAUTION: Possible Machine Damage! Do not use solvents other
than alcohol when cleaning the black polyurethane wheels.
10. If grime buildup exists on the PSA Seal rollers—
10a.Using a shop towel and alcohol or alcohol wipes, clean the
build up from the cover tape application rollers. Hold the
alcohol cloth on the roller and rotate the roller 360°.
10b.Repeat procedure for the other application roller.
11. Inspect the drive sprocket top idler and rubber O-rings for any
build up from the cover tape. See Figure 4-31.
12. If grime buildup exists on the idler and O-rings—
CAUTION: O-rings might be easily damaged. Handle gently to
avoid breaking them.
12a.Gently remove the two O-rings from the drive sprocket
idler.
12b.Using a shop cloth and alcohol or a commercial alcohol
wipe, remove all grime from O-rings.
12c.Wipe the idler clean.
12d.Reinstall the dry O-rings onto the idler.

Adjusting Pressure of the PSA Seal
Rollers
1. Advance the device tape with the cover tape through the Seal
Rollers using the manual advance pedal. Advance enough pock-
ets to correctly align the cover tape on the carrier tape.
2. Perform a peel back test by peeling the cover tape from the carrier
tape. Notice how well the cover tape adheres to the device tape.
Perform a twist test by giving the tape a slight twist. Notice if the
cover tape detaches from the device tape.
If either test produces loose cover tape, increase the application
roller pressure by screwing the PSA Seal pressure adjustment
screw in (clockwise).
If both tests look acceptable, visually inspect the sealed device
tape for adhesive that may have been squeezed out during
application. If adhesive is visible, the Seal Roller pressure is too
high. Decrease the application roller pressure by screwing the
PSA Seal pressure adjustment screw out and retest.
Troubleshooting the Tape Output
System
The Tape Output System contains sensors that detect these fault con-
ditions:
• a device is on top the device tape (carrier tape)—Track Jam Sen-
sor
• no cover tape is on the reel—Cover Tape Sensor
• device tape is not properly inserted in the device tape track—
Device Tape Present Sensor
• a pocket in the carrier tape is empty—Pocket Empty Sensor
When the AH700 software displays the error message Tape Out Unit,
one of the tape output system sensors has been triggered. The most
likely sensors to trigger are the Device Jam and Device Tape sensors.
See Figure 4-32 on page 4-58.

Use air to blow any debris out of the Device Jam
sensor path.
Adjust the Device Jam Sensor Controller. See Track

Replace the empty cover tape reel with a full one.
If the reel still contains cover tape, adjust the Cover
Tape Sensor Controller. See Track Jam Sensor and
Controller on page 4-59.
Pocket Empty Sensor

A Tape Out Unit error
message displays and a
red LED is illuminated
on the Pocket Empty
