Question about Zebra S4M Thermal Label Printer

1 Answer

Hi, The backing of my tag is a dark blue, and I'm affraid that inspite the fact that there is a hole that separates each tag, the reflective sensor is interpreting the dark blue color as a "mark" and my S4M printer is not able to set the label length. Any suggestions?

    Dan, This is the first time I'm using a S4M with these tags. I haven't set up any particular label length either . If the transmissive sensor wasn't a "fixed sensor", I could use it to sense the end of a tag, but then the sensor is located at around 11mm (??) from the border and it doesn't coinside with the holes on my tag.

A question first: Has this just started to happen or has this always been the case? Also, have you set up any particular label lengths or are you relying on the separator holes?

    The only potential solution to this is a recalibration of the sensors. Follow the proedure listed on page 72 of the user manual for recalibration. This should resolve the problem. If you don't have the manual handy, you can download it from teh link below.

Dusk to Dawn Light Adapter

Might work. Might not. Depending if the eye can sense light and dark from that position. If area is shaded, then the sensor might think it's dark earlier in evening. If the area is dark, then sensor will not do as well, or might stay ON full time.
If the outdoor light shines on nearby surface, the reflected light might cause photo eye to blink on-off throughout night.. or not function as expected.
You can add separate photo eye to any light, and choose location for photo eye.

Quick Fix for Ugly Nail Holes

Start by using the blunt end of a pen, or anything similar, and tuck any ragged edges into the hole so that the wall suface is flush and smooth again.
Now sneak into the kids' room and steal their crayons! No matter what color your walls are, you should be able to find a combination that will match the wall great.
Scribbling the crayon back and forth in every direction will fill the hole with crayon wax. Smooth it out between layers with your finger tip.
Start with a light color and darken to match. Baby blue with only a dark blue crayon? Fill the hole w/ white then lightly blend the dark blue in a little at a time. Maroon wall? Red then add brown. You get the idea.
When you're happy with the color just blend the excess away and your nail hole will be practically invisible.

Hampton bay exterior wall mount light fixture blinks after installation

If this is a unit that is supposed to turn on when it's dark, then the problem is that the sensor is "seeing" too much of it's own light. That is, when it get's dark it turns on, but the light it provides is telling the unit that it is sunrise and should be turned off. Find the sensor and cover it with tape, this will keep the light on. Now try to figure out where the brightness is that the sensor "sees". It may be a reflection from a nearby white surface. You might be able to redirect the lights (if they are reflector bulbs), or you might be able to paint the reflecting surface a brighter color, or you might be able to fashion a visor out of tape to shade the sensor from the reflected light. Good luck!

Gap not detected

GAP NOT DETECTED error in displayProduct: T5000rSymptom

GAP NOT DETECTED error in display.
Possible Cause

Dirty media sensors, wrong label length
Recommend Solution

Clean the upper and lower media sensors by spraying them with dry air. This should bedone every time the media (label stock) is changed.

Before running the Auto-Calibrate operation, check the QUICK SETUP or MEDIA CONTROL menu for the 'Label Length' parameter. It should be set to the length of the label, not counting the gap.

Check that the sensor type has been set in CALIBRATE CTRL menu to match the media and ribbon.
"Gap" Select when using media with a liner space between die-cut labels or when using tag stock with notches or holes as label length indicators.
"Mark" Select when using media that has horizontal black marks located on the underside of the label liner or tag stock.
"Advanced Gap" Select when media is gapped but also has a dark background.
This sensor arrangement looks through the ribbon, and will not work if ribbon is too dark.
"Advanced Notch" Select when media has a notch that is placed in a dark line on the back of the stock.

Check the position of the media sensor. It should pass through the center of gaps or marks or notches, but not through pre-printed areas if possible.

Run Auto-Calibrate in CALIBRATE CTRL menu, which sets Gap and Paper Out Thresholds

Where are the cam sensor and crank sensors located on my car?

Crank Sensor: Passenger side of transmission just to right and above the differential cover. Has 3 wires:

Light Blue/Dark Blue stripe - Signal
Dark Red - 8v supply
Black/Light Blue stripe - Ground

If the car runs or cranks, you can test this sensor by first checking for power on RED wire with key ON. Should be 8-9.5 volts DC. Furthermore, connect a dwell meter to the signal wire by probing the back of the connector. Dwell reading should be 49-51%. If not, its likely bad.

If you remove the sensor, you MUST replace the paper spacer on the end of the sensor or you risk damaging the sensor or even the torque converter drive plate otherwise. Also make sure O-ring is in good shape and positioned properly.

Cam Sensor:
Facing Engine, it is on the driver side timing case housing, on top of the round part, just to the right of the fuel rail pipe where there is a capped fuel valve.

Has 3 wires:

Tan/Yellow stripe - Signal
Dark Red - 8v supply
Black/Light Blue stripe - Ground

Testing is same as for Crank Sensor.

Print jam on the thermal TEC B-572 TXP -3.5

The purpose of the knob if to change the position of the sensor. If you look at the sensor when turning the knob you'll find out that it moves forward (towards you) or backwards (away from you) This should allow you to place the sensor at the correct position. Further more, there are two holes on the plastic flag. the hole nearer to you is the transmissive sensor and the other is for reflective. Try to place the sensor at the correct position.

Color transparencies are dark & poor color


Nice printer.. Hope this will give hints. Considering transparency papers, please try another batch of or a piece of transparency paper. Try to adjust also the graphics preferences (dark to light) aside from transparency paper selection. Have a nice day.

Trouble printing a thicker form

I have come accross this problem on a number of sites. It may be the Paper Out sensor. It works by emitting light from one half of the sensor reflectiong it of the paer and picking it up with the other half of the sensor. When no paper is present, the light cannot reflect and hense a paper out error is reported. I have seen this error occur when paper with dark backing ( like that for bank and tax forms ) is used.
