Why does paper not advance to next line when carriage returns?


There might be a setting for how many lines it moves when the carriage gets to the end. It is mechanical so you'll see it!

Problem with the line spacing on my brother sx-4000 typewriter. The spacing wheel is not moving the paper down to the next line. I've moved the lever on the right side back and forth to see if it...


If all the settings are right and it feeds with the platen knob the plastic gear on the index mitor is probably broken the part is about 25.00 plus installation.

How do u remove the roller bar that the paper feeds thru if something is stuck underneath it?


Step 1

(1) Pull off the platen knob 1.

(2) Open the access cover Assy 4 toward the front to remove.

(3) Lift up the sheet guide Assy 5 to remove.

(4) Turn the change lever 2 toward the bottom position.

(5) Insert a flat-blade screwdriver into grooves of frame (5 places for ML 321, 4 places for ML320) and twist to disengage claws of upper cover 3.

(6) Raise the front side of upper cover Assy 3 and shift toward the rear to disengage claws of frame (6 places for ML321, 5 places for ML320).

(7) Raise the upper cover Assy 3 to remove.

(8) To install, follow the removal steps in reverse order.

Note on installation:

Match the posts A at both sides of the sheet guide 5 with the arrow marks on the upper cover. Push the guide into the cover.

Step 2

(1) Open the access cover 1.

(2) Lift up the sheet guide Assy 4 to remove.

(3) Tilting the pull-up roller Assy 2 toward the front, remove it from the shaft of platen Assy 3.

(4) To install, follow the removal steps in reverse order.
Note: Remove the sheet guide Assy 4 before installing or removing the pull-up roller Assy 2.

Step 3

(1) Open the access cover.

(2) Pull up and rotate the head clamp 1 to unclamp the printhead 2 as shown in fig. 3.3.1.

(3) Disconnect the printhead 2 from PC connector 3 and remove.

(4) To install, reverse the removal steps.

Notes on installation:

(1) Insert the printhead 2 into the PC connector 3 while pushing it against the carriage frame 4.

(2) The head clamp 1 must be securely sandwiched between printhead 2 and carriage frame 4 as

shown in fig. 3.3.2 below.

(3) Be sure to check the gap between platen and printhead (see 4).

(4) Be careful not to touch the print head while it is hot.

Important: There is a shim on the carriage frame 4, which hangs over the platen side of the frame. Be sure to replace it correctly. Improper positioning of this shim will severely affect the printhead gap.

Step 4

(1) Remove the printhead (see 3.3.1 below).

(2) Open the pull-up roller cover 1.

(3) Remove the shim on the carriage frame.

(4) Loosen the screws holding the carriage assembly to the carriage frame--this allows more play between the printhead and the platen.

(5) Raise and remove the ribbon protector 2.

(6) To install, follow the removal steps in reverse order. Be sure to replace the shim in exactly the

same position as it was before disassembly.

Step 5

(1) Remove the printhead (see 3.3.1 ).

(2) Remove the upper cover (see 3.3.1 ).

(3) Remove the pull-up roller Assy (see 3.3.3 ).

(4) Remove the ribbon protector (see 3.3.2 ).

(5) Turn the change lever 1 to the bottom position.

(6) Push in the lock levers 2 on both sides to unlock the Assy from the frame, then rotate them upward 90°.

(7) Remove the platen Assy 4 from the base frame.

(8) To install, follow the removal steps in reverse order.

There's a hidden sensor lever under the white guides behind the platen roller. Either a scrap of paper is holding it up, or it could be bent from pulling out a jam. It is a black lever behind the platen roller slightly to the right of center. You may need a shop to repair.

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 print is only clear on the left side of the forms...


Platen Gap Adjustment (Figure 35)
IMPORTANT Only do this procedure if the original equipment shuttle frame assembly or platen has been replaced by a new or
refurbished unit.
1. Prepare the printer for maintenance (page 338).
2. Remove the shuttle cover assembly (page 357).
3. Loosen the platen open belt (page 415, steps 2, 3, and 4).
4. Raise the forms thickness lever (1) to the fully open position.
5. If you are adjusting any model except the 6400-i20, select a 0.011 inch (0.28mm) flat feeler gauge.
If you are adjusting a 6400-i20, select a 0.012 inch (0.30 mm) flat feeler gauge.
ATTENTION Do not force the platen against the feeler gauge. Damage to the hammer tips will result.
6. Insert the feeler gauge (2) straight down between the hammer bank cover plate (3) and ribbon mask (4), within four
hammer positions of the left end of the hammer bank.
ATTENTION Adjust the platen set screws less than 1/4 turn on one side, then check the other side. Adjustment sensitivity is
approximately 0.03 inch per revolution of the set screw. Also, insert the feeler gauge no more than two inches down
from the top of the ribbon mask.
7. Gently close the forms thickness lever (1). As the platen is closing, gently slide the feeler gauge up and down, keeping it
between the hammer tips and ribbon mask. If the feel is too tight as the platen closes, adjust the 3/32 inch set screw (5)
counterclockwise. If the feel is too loose, adjust the set screw clockwise. With the forms thickness lever closed all the way,
the feeler gauge should contact both the tips and the ribbon mask and move with light friction. Shift the gauge slightly to
verify.
8. Repeat steps 4 through 7 at the right end of the hammer bank.
9. After adjusting both sides, check the gap again at both ends. Readjust if necessary.

Daisy wheel will not stay on wordsmith 100



CHANGING Changing The Ribbon Cassette 1) Move the print carrier to the center of the platen using the SPACE or BS key. 2) Hold the ribbon cassette on both sides and lift up the front portion (where the ribbon is exposed) to remove the cassette. 3) To insert a new cassette, place the back end of the cassette on the cassette holder on the carrier and gently press down on the front of the cassette unit it clicks into place. 4) Turn the ribbon feed knob counter-clockwise again to take up any slack in the ribbon. 5) Presss the CODE + = (SETTING) key.

Changing The Print Wheel 1) Move the print carrier to the center of the platen using the SPACE or BS key. 2) You will see a lever on the right side of the carrier. Pull this lever toward you and lift out the daisy wheel. 3) Place the daisy wheel into the slot with the characters facing the platen. 4) Push the lever back into position. 5) Press the CODE + = (SETTING) key.
It appears as though you have something that is preventing the print wheel from being locked in place by the release lever. It should make a snapping or similar noise when it is locked down.

Paper advance


The paper release lever may be in the release mode. try holding the left platen knob and pulling lightly on the paper is should not allow the paper to move freely, if it is ok try holding the left knob and turning the right knob in the direction you would to turn the paper in it may have come loose if so turn it all the way back in do not over tighten it your machine does not click when the platen is turned it uses electronics to hold the platen on line.
