The 2.5-inch LCD display is fitted in the center of the clearly arranged controls. On the left are the on / off switch and the buttons for copying, faxing and scanning. On the right is a handy scroll wheel for quick scrolling in the menus on the display. On the right are also the usual buttons for menu, settings and navigation and the numeric buttons arranged. Canon also provides a special button for copying and printing photos directly from the memory card via the card reader, and integrates a few smaller buttons that automatically select preset fax numbers.
Canon offers two different ways to feed the MX870: The paper drawer, which can be pulled out under the output flap, can accommodate 150 sheets. Another 150 sheets can be inserted in the rear cassette. Both cartridges feature small plastic guides for a variety of media sizes from 10x15 centimeters to A4 size paper and envelopes.
The scanner unit is located in the center of the printer and can be folded up to access the MX870's five ink cartridges (four color inks and one pigmented for black printing). According to the website of Canon, a replacement color cartridge costs 11.49 euros and a black cartridge 12.49 euros. Canon estimates the price for printing a black and white document at 3 cents, a full-color document costs 5 cents, and a color photograph in the format 10 × 15 centimeters 29 cents. This is the average price for modern photo printers.
Fortunately, the MX870 also includes a memory card reader, unlike the Canon Pixma MX330. The card reader is located at the bottom of the printer to the right of the paper exit slot and contains slots for MemoryStick Duo, SD, and Compact Flash cards.
After inserting a memory card, the MX870 offers two printing options: you can either select multiple photos via the navigation pad and batch print or view, edit and print individual images directly on the LCD screen. Manual editing features include the reduction of the red eye effect, color effects such as sepia and black and white, the reduction of noise and image enhancement. Finally, a PictBridge compliant right-side USB port allows you to connect a compatible digital camera directly to the printer.
