Canon Canon PIXMA G7020 MegaTank Wireless All-in-One Inkjet Printer with ADF and Fax 1641 Error Fix: Support Code 1641 — Ink Has Run Out (MegaTank)

Error code 1641 on the Canon Canon PIXMA G7020 MegaTank Wireless All-in-One Inkjet Printer with ADF and Fax means: Support Code 1641 — Ink Has Run Out (MegaTank). The printer has detected that one or more ink tanks have run out of ink. On MegaTank models, the ink level is monitored visually through the transparent tank windows on the front of the printer and by the printer's internal counter. Refill the depleted tank(s) with Canon GI-20 ink bottles — each color has a keyed nozzle that only fits the correct tank opening to prevent mixing. Fill to the upper line but do not overfill. After refilling, you may need to reset the ink level counter from the Setup > Ink Level Reset menu (process varies by model). If the error persists after refilling, run a cleaning cycle to prime the ink system. Air bubbles in the ink supply line can prevent the printer from detecting ink properly.
