Clean carriage wheels (monthly)
Ink dust and debris can accumulate on the carriage wheels. These particles become obstacles and
friction for the carriage wheels, which can appear as repeating output anomalies on the printed media.
There are four carriage wheels to clean (A, B, C, D in the figure below). The lower pair of wheels (E, F)
are not accessible.
1. Raise the rail by selecting the following from the printer’s menu: Tools > Service Printer > Reset
Home Positions > Reset Rail Home Position.
2. Clean the top service-end wheel by placing an IPA (Isopropyl alcohol) moistened cotton swab
against the side of the wheel (A in photo below) and moving the carriage back and forth about 10
cm (4 in).
3. Clean the top user-end carriage wheel with an IPA moistened cotton swab.
