4.4.1: Printhead
The printhead should be removed and cleaned approximately every 4-6 months depending
on usage. Deterioration of print quality between scheduled cleanings would indicate a need
for more frequent cleaning. To remove and clean the printhead proceed as follows:
1. Remove top cover (see Paragraph 4.5.1).
2. Remove printhead (see Paragraph 4.5.24).
3. After removing the printhead and bracket assembly from the carriage, clean the
head using a small hard-bristle brush and isopropyl alcohol. Only the printhead
should be cleaned including the wire tips and jewel bearing. All ink and ribbon
fabric residue should be removed in this process. Do not attempt to clean inside the
printhead case or around the cylinder the printhead coils.
4. Replace in reverse order.
