Clean the scanner as
described in paragraph 3 .2,
demagnetize or replace the
MT and make a new copy
Instructions on Repair
Cleaning the tape drive of the Optic-Mechanical Block tract
Cleaning the tape drive of the Optic-Mechanical Block tract is done when it is polluted with
foreign objects, impeding the magnetic tape travel . The same is applied to the MT extraction ,
when it was jammed during the automatic injection or reverse motion . Such jamming is
possible when the user does not observe the recommended edge form of the magnetic tape
strip (see paragraph 2 .2 .2 .2) . The OMB tape drive clearing and the MT extraction shall be
performed in the following order:
{
turn the front side of the device, when in the working position, to the operator
(see Figure 1),
{
release the pinch roller fork (see Figure 3, pos . 5) . Insert a thin core into an aperture
(Figure 11) and slightly press – until the lever of the roller is released,
