Well, the answer is no !! First time yes, but as the paper advance seemed to stop at the head I removed it… big mistake !!! Without the printing head circuit, the head carrier cuts the fabric !!! I damaged it when the printer did try to do a paper advance…

The head must sit regularly and flat inside the frame. To mount it properly you have to press back the platen that is in the upper part near the fabric. Then it (EDIT: the print head) snaps into place.
Picture in g) and k), l) in section 7 on page 22 of the Service Manual. The pictures are very good if you load from https://literature.hpcalc.org/items/410
No. 17 - platen - on page 7-5.
