This is very simple. Just replace Stripper pad and Pickup rollers. Also there are adjustment in stripper unit. Check the green circle knob and adjust in to move the stripper pad in different angle. You need to do this every several thousand copies to even the worn in this rubber pad. If you continously make copies without adjusting it, only one side of stripper pad will be worn out and it will repeatedly make double feed and eventually cause jamming.

Replace the stripper base, pad and metal cover. www.image-parts.com has the best stock I have seen yet. "Stripper Pad 3750" 019-11933 is the clear type pad, and the "Stripper sheet: Green" 019-11731 is the type that does not need the cover. I don't know how the uncoated or "(Shrt)" are. I recommend the base 019-11733 and cover 019-11734 with the 019-11933 clear as it has lasted for 10 years on those part combinations and about 250K prints.

My 1900 printer power is on and flashing slowly and the paper/garbage light is on and not flashing.


Hello.

You most likely have a paper jam or a paper feeding problem. Paper may have jammed in the sheet feeder, manual feed slot, or roll paper slot.

Sheet Feeder or Manual Feed Slot: Press the
paper button to eject any jammed sheets, then open
the printer cover and remove any paper jammed inside.
Press the paper button again to clear the error.

Hope this helps.

MP830, how to retrieve faxes in memory to my PC


-

- A margin appears
on printouts.
2 B Paper feed
Improper paper
feeding:
- Multi-feeding
- Skewed paper
feeding
- Paper jam
- Paper feeding from the
ASF
- Plain paper
- Highest print speed
(Custom setting to 5)
- In the high temperature
and high humidity
environment
- In the low temperature
and low humidity
environment
- With the maximum
amount of paper set (13
mm)
In the high temperature
and high humidity
environment, paper
becomes wavy; in the
low temperature and
low humidity
environment, paper
curls significantly.
When the maximum
amount of paper is set
in the ASF, and if the
paper-return tab fits in a
wave or curl of the
paper, the tab slips and
does not catch paper
properly, causing paper
feed problems.
- Reduce the amount of
paper set in the ASF to
half (approx. 5 mm
high).
- Multiple sheets of
paper feed at the
same time.
- Paper feeds at an
angle.
- A paper jam
occurs.
3 C Print results
Skewed paper
feeding (at the
level of +/- 1%)
- Paper feeding from the
ASF
- Credit Card size
Since coaxial tolerance
between the pinch roller
and the LF roller, which
determines the paper
feed alignment, is
0.2mm, skewed paper
feeding can occur.
However, according to
the field data of current
models, the skewness
level caused by the
coaxial tolerance of
0.2mm is within the
criteria of +/- 1%, thus
the phenomenon is left
as is.
- Align the paper guide to
the paper edge tighter
than usual.
- Paper feeds at an
angle.
- A margin appears
on printouts.
4 A Print results
Soiling on the
back side of paper
(lines or streaks
parallel to the
paper feed
direction)
- After continuous
borderless printing of
small sized paper (such
as 4 x 6), when a larger
sized paper (such as A4)
is printed.
- With Photo Paper Plus
Double Sided or
postcards, the
phenomenon is likely to
be noticeable and to be
complained of by users,
as printing is performed
on both sides of such
paper.
In borderless printing,
printing is performed to
the size slightly larger
than the paper size, and
ink off the paper is
absorbed by the platen's
ink absorber. Absorbed
ink may attach to the
platen rib(s) after
several dozen sheets are
printed, causing soiling
at the leading edge of
paper or on the back
side of paper.
1. Perform Bottom plate
cleaning (from the
MP driver or via the
operation panel) up to
3 times*1.
2. If soiling on the paper
still remains after 3
times of Bottom plate
cleaning, wipe the
platen rib(s) and their
surroundings with a
cotton swab.
- Paper gets
smeared.
- The back side of
paper gets
smeared.
Soiling on paper in
automatic duplex
printing (lines or
streaks
perpendicular to
the paper feed
direction)
- Automatic duplex
printing (Photo Paper
Plus Double Sided,
postcards, plain paper)
On the rib(s) inside the
sheet feed unit used for
duplex printing, ink
mist may accumulate,
smearing paper.
Temporary operational
solution:
Cancel automatic duplex
printing, and manually
print each side of paper.
Cleaning by user:
1. Perform Bottom plate
cleaning (from the
MP driver or via the
operation panel) up to
3 times*1.
- Paper gets
smeared.
- The back side of
paper gets
smeared.
- Even after Bottom
plate cleaning
was performed,
and the platen
ribs were cleaned
with cotton swab,
paper gets
smeared.

The printer will not feed the paper into the machine


Hmm, this is too general symptom too troubleshoot. But never mind. Printer cannot feed the paper for several reasons:
Auto sheet feeder (paper feeding mechanisme) is faulty;usually generate error message on the monitor or/and error code on LCD display
Paper end did not reach paper sensor because the paper not set properly or another material block the paper path.
To find out more about this error,please check the following article exclusively for Canon printer.

The duplexing option is not working. it will print on the one side, but as it is pulling the sheet back in, it will get stopped up and the rollers will spin until it errors out. it appears to be getting...


Firstly, it may not be the machine. It is possible that your paper is damp and once the machine has printed on one side the texture of the paper changes causing the machine to struggle when feeding it through the duplex unit. Other wise the plate at the back will have rollers above it feeding the paper that may well be dirty causing it to fail when feeding. Check for obstrux=ctions and clean any roller you can find in the duplex unit.

Paper doesn't feed


It could be a few things, but the times I've had similar problems it was either caused by the feed/gripper rollers in the paper trays being worn out, thus not feeding any paper or feeding half a sheet and then jamming.

Or, it could be that the elevator in your paper tray isn't lifting, but if it's taking paper it's probably the rollers.

Uneven paper feeding


Normal 0 I suggest you get a sheet of Card Stock (Heavy paper) and place it in the feed way. Then press the print button applying a slight amount of pressure on the Card Stock so it will feed through the printer. The reason for this is in some cases I have been able to clear the paper track of debris that was deposited there over time.
Worth a try, as I have fixed a number of printers this way, saving costly repairs.
Hope this helps. Bud
