To clean the heads open the CQ sachet, which already contains the necessary cloth and cleaning agents. Leaving the cloth folded, place it against the drum (the easiest place is on the right-hand side of the drum) and hold it gently in place with your index finger. While applying GENTLE pressure to the drum rotate the upper half or scanner ANTI-CLOCKWISE 20 times, using the round rotor board that is secured to its top.
(We repeat, it is very important that you do not move the cloth or your finger while you are rotating the scanner as this can damage or affect the alignment of the heads.)
This has the effect of swiping the heads through the material and the cleaners, which dissolve out the embedded oxide and debris, depositing them onto the cloth. The result is a dark smear on the material. Continue cleaning until no more residues appear on the cloth, do not let the cloth dry out.
The helical groove around the top of the lower drum should also be cleaned. As this does not spin a cotton swab moistened with alcohol will suffice. As you clean this groove, rotate the upper drum a little to keep the heads away from the swab.
Do not allow the cotton swab to come into contact with the heads.
Wait for two or three minutes to allow the alcohol to evaporate before inserting a tape, failure to do this will result in a tape tangle.
Test the recorder while the mechanism is still exposed to be sure that the tape plays satisfactorily and that none of the indicators described in the first section of these instructions is present.
Having completed the head and tape path cleaning and tested that the recorder is operating correctly, replace and secure the top plate or cover of the ADAT, return the recorder to its normal position and reconnect the mains power, audio and control cables.
