I don't know how to fax

The control panel LCD also provides menus to operate the copy and fax modes independently of a PC. One nice touch: the LCD displays small and large type on the same screen, allowing more information about a print job to show at one time. b.gif 21262659-2-200-dt2.gif
The flash card reader under the control panel means you don't need a PC to print photos.

The MP730, while easy to operate, lacks some of the advanced features you might find on separate printers or faxes. For example, the MP730 can't collate copy jobs. To make more than one collated copy of a multipage document, you have to place the document in the ADF several times. Nor can the MP730 sync fax numbers entered by hand or accessed from within the Windows Address Book (Canon doesn't provide its own fax/address-book software), so you may end up duplicating efforts. Nor does Canon's software create group dials from your address book on your PC or provide a cover sheet. Finally, the MP730 can't forward faxes to another number or hold a fax to send when nighttime low rates kick in, which other multifunctions do.

Still, the MP730 provides plenty of features we do like. Using the menus with the Photo Print mode, you can print a photo contact sheet, pick individual images to print, and set up the printer to copy or print onto high-quality glossy paper. In the Copy mode, menus let you print two reduced originals side by side or print the same image on the same page several times (useful for business cards, name tags, and so on). The fax engine distinguishes voice from fax, sending voice calls to your phone or an answering machine and sending fax calls to the printer or to buffer memory so that you don't have to get a second phone line installed for your fax.

Installing the MP730 software is slow but idiot-proof: You just pop in the CD and follow instructions, which require restarting your PC several times. Canon bundles the MP730 with ScanSoft's OmniPage SE, a lite version of the best optical-character recognition software on the market, and NewSoft's Presto PageManager 6.0, one of the best document-management databases available.
The MultiPass MP730 won't replace top-of-the-line printers and scanners, but its print and scan speeds keep up with other multifunctions' as well as that of most as midrange ink-jet printers and scanners on the market today. In our tests, it printed ordinary text at 6.4 pages per minute and printed CNET's high-resolution test photo in 3.7 minutes. For comparison, the Lexmark X5150 (only $149 but without fax capability or automatic document feeder) prints text at a more common 5.2 pages per minute, and printed our test photo in about 2 minutes. Canon's MP730 scans a page of black in 9.4 seconds and a page of color in 20 seconds; that's seconds faster than the HP PSC 1210. And the Canon makes copies in 18.7 seconds; that's almost twice as fast the HP PSC 1210.

Unfortunately, the MP730 delivers a mixed bag on image quality. When printing, better paper has a big effect. When we printed text on ordinary paper, for instance, it looked grayish instead of black, and a gray shadow haunted the edges of letterforms, while on coated (not glossy) inkjet paper, text popped out in a solid black and looked much cleaner. Our color photo on ordinary paper looked very dotty, had rough transitions between shades, made a blob of detailed areas, printed lines with jagged edges, and mixed inappropriate colors; coated inkjet paper improved detail and let colors appear in the right hues, though much too saturated. And on top-quality glossy paper, textures, shading, and transitions suddenly looked right, and we saw sharp, clear detail.

Grayscale scans on the MP730 when compared with other scans seemed overexposed, losing paler shades of gray along with some detail, while color scans showed accurate colors and fairly good detail despite somewhat grainy textures.

Canon MP460 smears ink on back of printed copy

Look where the heads park--there should be a sponge-like pad under the heads that wipes them clean. Remove the pad (wear rubber gloves--very messy) and either replace it or clean it in detergent and hot water. Squeeze out and let dry.

Hello sir;Did you reset copier after you replace a new drum? if not please do it, if still have problem, you need adjust shading;
Close doccument feeder, select adjust shading . press "set up" An image will be scanned and a ccd shading profile will be print put, if the printed image is different than the image the ccd is bad.

Diagonal shading problem on monochrome print

I would try cleaning the lasers with the brush inside the door. If that fails, you might try looking at the developers.
