I have scanned some pages regarding drive head cleaning from Apple II
Plus/IIe Troubleshooting & Repair Guide (by Robert C. Brenner) here:
http://apple2.sytes.net/Floppy_Maintenance

IIRC there are other sections related to calibrating disk ]['s, but
unfortunately I haven't got around to scanning them in yet. Let me
know if this would be useful to you and I'll see if I can make time to
do the scanning.

Cheers,
