An imprinter mechanism, which prints text (5 lines) or a Bitmap on documents as they are scanned, comes standard with Canon imageFORMULA Check Readers. The Bitmap specifications are very specific as shown below. If you don't follow these guidelines you may receive an error "File Can't be Opened" when trying to attach the Bitmap file on the imprinter setup page.
Turn the device’s power off and unplug from power source and/or remove the battery (for mobile printers). Clean the exterior components of the device using a line lint-free cloth moistened with 70-80% isopropyl or ethyl alcohol. Do not spray or apply alcohol directly to the product.
