    Is there a way to make copies solid instead of grayscale on this machine. Copier does not do a solid black everything has a white dot.
    Service tech says it's my files from my computer, but even if you copy off the glass still has dot.

I have used last 4 year canon 2900B printer. How to set 300 dpi printing resoluation


Canon PIXMA Manuals MG2900 series Resolution
Resolution The data in the image you have scanned is a collection of dots carrying information about brightness and color. The density of these dots is called "resolution", and resolution will determine the amount of detail your image contains. The unit of resolution is dots per inch (dpi). Dpi is the number of dots per inch (2.5 cm). The higher the resolution (value), the more detail in your image; the lower the resolution (value), the less detail.

How to Set the Resolution You can set the resolution in Resolution on the (Scanning from a Computer) tab of the Settings dialog.
Appropriate Resolution Settings Set the resolution according to the use of the scanned image.
Item Type Use Color Mode Appropriate Resolution Color photo Copying
(Printing) Color 300 dpi Creating a postcard Color 300 dpi Saving to a computer Color 300 dpi Using on a website or attaching to e-mail Color 150 dpi Black and white photo Saving to a computer Grayscale 300 dpi Using on a website or attaching to e-mail Grayscale 150 dpi Text document (document or magazine) Copying Color, Grayscale, or Black and White 300 dpi Attaching to e-mail Color, Grayscale, or Black and White 150 dpi Scanning text using OCR Color or Grayscale 300 dpi Important
  • If you double the resolution, the data size of the scanned image quadruples. If the file is too large, the processing speed will slow down significantly, and you will experience inconvenience such as lack of memory. Set the minimum required resolution according to the use of the image.
Note
  • When you will be printing the scanned image by enlarging it, scan by setting a higher resolution than the recommended one above.

SC 329: Laser Beam Pitch Adjustment Error
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

The LD unit home position sensor does not detect an on condition while changing the LD unit position for correcting the LD position or changing the DPI.


Instructions from the Service Manual below...

.

5.4.3 LASER BEAM PITCH ADJUSTMENT
There are two laser beam pitch adjustment procedures: one for 400 dpi, and one
for 600 dpi. These adjustments use the following SP modes.
· SP2-109-1: Laser Beam Pitch Adjustment - 400 dpi
· SP2-109-2: Laser Beam Pitch Adjustment - 600 dpi
· SP2-109-3: Laser Beam Pitch Initial Setting - 400 dpi
· SP2-109-4: Laser Beam Pitch Initial Setting - 600 dpi
· SP2-902-2, no.12: IPU Test Pattern - Cross Stitch - 400 dpi
· SP2-902-2, no.13: IPU Test Pattern - Cross Stitch - 600 dpi

1. Perform SP2-109-8 (Beam Pitch Data Reset).

2. Input the value for 400 dpi that is printed on the LD unit into SP2-109-1.
Use the value printed after "P" on the new LD unit as shown below.
NOTE: Do not use values printed after a "V".

(These value numbers are on a sticker inside the machine with a UPC code on it. The numbers are just under the UPC barcode. And example number looks like this: "15980300151P: 120, 172", so the example 400 dpi value here is "120".)

3. Press the "Enter" key.

4. Perform SP2-109-3.

5. Print the 400-dpi test pattern onto A3 (11"x17") paper using SP2-902-2 no.12
(cross stitch). (See Service Tables - Test Pattern Printing - Section 4.2.3, pasted below.)

6. Write the value of SP2-109-1 on the test pattern which was input at step 2.

7. Change the value of SP2-109-1 and print another test pattern, repeating steps
2 to 5. Print about 5 patterns with different values for SP2-109-1 (e.g. "48", "96",
"192", "240").

8. Check this test pattern. If the laser beam pitch is not correct, the image looks
like a black vertical stripe pattern.
NOTE: If the laser beam pitch is correct, the vertical stripe is not so noticeable.
If the value is not correct, the vertical stripe pattern is darker.

9. Adjust the laser beam pitch position until the thin lines are of uniform thickness
(no striping effect should appear on the printout), doing steps 2, 3, and 4. (In
step 2, input a value which is estimated to be correct, then do steps 3 and 4,
then if necessary go back to step 2 and try another value.)

10. After adjusting the laser beam pitch for 400 dpi, adjust the laser beam pitch for
600 dpi, using the same procedure as for 400 dpi (use the SP modes for 600
dpi).

.

4.2.3 TEST PATTERN PRINTING (SP2-902)
NOTE: Do not operate the machine until the test pattern is printed out completely.
Otherwise, an SC may occur.

1. Access the SP mode which contains the test pattern you need.

2. Press exit, then touch the "Copy Mode" key on the operation panel to access
the copy mode display.

3. Select the paper size.

4. Press the "Start" key to print the test pattern.

5. After checking the test pattern, exit copy mode by touching the "SP Mode" key.
Reset the test pattern to 0.

6. Exit the SP mode.

These adjusments listed in the manual require removal of a service panel and mechanical adjustment of the laser mounts, so it should be done by a qualified technician.

However, these test procedures can indicate whether or not this is the problem with your printer.

Copies are being printed with a line vertically down the side of the page. Only happens when copying using the hopper.


If it's a thin, sharp line, it's just a blob of ball-point pen ink on the scanner glass. Lift the lid, and you'll see the narrow strip of glass that the scanner uses when you feed a document through the feeder. Clean that with a rag dampened with window cleaner, or, better yet, alcohol. Even a dot of ink too small to see will show as a solid black line on anything you copy, scan, or fax via the doc. feeder.
Don't use so much cleaner that it runs under the glass.

I just got a hp photosmart c4480 printer and it makes black and white copies, but I can't figure out how to print in black and white like when I am on a web site.


OK, Whe you select Print from the File Menu and the Print window opens, selct the Color tab.

There should be an option to Print in Grayscale. Check the box beside it and click OK at the bottom. Then back at the Print window, click Print.

(Note: If this option is not on the Color tab, or you do not have a color tab, look on the Advanced tab for the same thing.)

Thanks for using Fixya.

Copying with 4" solid black vertical stripe


what about if you print from computer or do an internal print like a self test? if print looks good on those, you most likely have a scanner problem, which is the mechanism under the glass.

Black line on document when I scan from platen or ADF or scan to save as PDF.


As a tech I've never seen that happen. from the doc feeder only Yes, not both the feeder and the glass but not show up when you print from the computer ?????????

For sure there is a dot or something on the small strip of glass, only when you do it from the feeder.
the reason is that the document is moving and the dot on the "small" strip of glass now looks like a line to the copier.

You said it also does it when you lay it down on the glass !!??(platen) that should of indicated the drum has a ring around it, but since it doesn't come out on the PC copy then the glass must have a line on it.

Copy problems


1-if you make a copy on the glass instead of the feeder is it still there?
If no, then clean small 1" glass on copier there is a spot on it. even a pencil or pen dot WILL make a line on all copies. easiest way to find it, line up the paper on the small strip of glass and follow there will be something there ( sometimes it's hard to see since the background is black)
2- the drum has a black toner ring around it replace the drum blade or drum unit

Scanned documents are very light


I have found that when scanning b/w documents, its helpful to start with a black and white copy, not a grayscale, pen written, or printed form a printer in grayscale mode copy, but a true black and white on the copier or fax copy. The scanner doesnt read shades of black so well and when scanning multiple page documents, my pixma tends to scan in lightly. I havent found a piece of software to do just this, batch darken what has been scanned (at least not for free). Copying before scanning is the work around. Hope this helps everyone who's had this problem. It also doesnt hurt to darken what your scanning down a notch when copying

Problem while copying


O.K. guys,

the problem is with the smaller glass on the left.
Lift the top and look at the small glass on the left, is there a dot, whiteout, dirt etc... on there? that is what's making your lines. clean with alcohol or mild cleanser.
