A4 Thermal Fax Paper for Reliable Office Printing

Mientras que muchas oficinas han cambiado al intercambio digital de documentos, Hospitales, Oficinas gubernamentales, Hoteles, Estaciones logísticas, Las oficinas financieras y los centros de servicio remoto siguen utilizando máquinas de fax térmicas. These machines are easy to use and can accept any documents, even if they are not toned or have no ink.

Sin embargo, they are very reliable, depending on the paper. The wrong roll width, Diámetro del rodillo, coating direction or surface quality of A4 thermal fax paper can result in blank, faint or repeated paper feeding or paper curling problems.

For procurement departments that are dealing with legacy fax machines, the right paper is not necessarily the lowest cost roll of “A4” paper. Machine compatibility, image quality and storage conditions and continuity must be considered as a whole.

A4 Thermal Fax Papel is Typically Roll Fed.

A4 is typically a sheet of paper 210mm × 297mm in size. In a thermal fax machine, sin embargo, A4 paper is normally provided as a roll of paper with a width similar to the width that the machine can print. The fax machine pulls in the necessary length and cuts or tears the finished product.

This therefore indicates that two pieces of ‘A4 thermal fax paper’ can have:

• Roll widths
• Roll lengths
• Outer diameters
• Core diameters
• Paper weights
• Coating sensitivities
• Coated-side orientations
• Packaging quantities

There are portable thermal document printers available which use sheets or folded media rather than the typical fax rolls. It is therefore advisable that buyers check the original paper and the operating manual in the machine's media compartment before replacing the original paper.

For more information on full-width thermal media for office document and mobile printing, please refer to Jin Bao Brother's A4 thermal paper guide.

Please Check the Papel before Selection of the Machine.

Thermal fax machines use heat to create images on a paper coated with a heat-sensitive material. Usually do not need a printing ribbon, ink or toner.

The heat sensitive layer is the layer that should be oriented towards the printhead and loading the roll upside down could cause a blank page. One indication of a coated side is a moderate scratch which will normally create a dark mark on the heat sensitive surface.

There are more things to consider than the appearance when it comes to smoothness.

Direct thermal printing is a printing method that involves moving the paper close to the thermal printhead. Fuzzy and unevenly coated fibers, or rough surfaces can cause increased friction and uneven contact.

A good thermal fax paper (A4) should offer:

• Uniform surface smoothness
• Even thermal coating
• Low paper dust
• Cleanly cut edges
• Stable paper thickness
• Stiffness for adequate feeding
• Predictable heat response

The surface may be uneven and result in areas of darker and lighter spots. Too much dust or coating residue can build up on the printhead and feed rollers, causing streaks, or even blanking out sections.

The article about A4 thermal copy paper surface properties at Jin Bao Brother helps to understand the impact of fibers, coating coverage, calendering and surface particles on the thermal printing and contact between the printhead.

Check Density at Normal Fax Settings on Test image

It can be a very sensitive coating, resulting in dark output with low print energy, or a less sensitive coating that demands higher heat, or slower print speed. Each characteristic should be assessed with reference to the real fax machine.

Evaluation samples should contain:

• Small text
• Solid black areas
• Líneas finas
• Signatures
• Tables
• Gray images
• Full-width content

The whole document should be legible from the beginning to the end of the roll. Pale vertical bands can be caused by poor contact at the printhead, variation in coating or the printhead contamination. Dark gray background can be a sign of too high heat sensitivity and/or improper storage.

If the organization has multiple types of fax machine, testing should be done on multiple machines. A paper that is successful in one unit may not do the same in old equipment or equipment that sees a lot of use.

Handle the control of Curl, Cutting and Document Handling.

Fax paper has a core that it is wound around for long periods and thus has a natural curl. Too much curl may make it hard to stack or scan, sign or file documents.

Quality of cut is of the same importance. Rough edges can cause dust to cling to the cutter and uneven cutting can cause the length of the pages to be inconsistent. Completed pages should come out without sticking to the roll or folding-up inside the machine.

If you're one of those organizations that scans inbound faxes as soon as they arrive, then medium curl might not be an issue. Improved flatness is desired for documents to be signed, copied or physically filed.

Request a picture of the life they want.

Thermal fax imaging is produced by the chemical reaction in the coating. Gradually darkens or fades when exposed to heat, ultraviolet light, aceites, Alcohol, adhesives or plasticizers.

A4 thermal fax paper could be employed to save communications records in the short and medium-term, but should not necessarily be regarded as permanent archival paper.

Buyers should ask for image-stability test data and test the print over realistic time periods if the original printed fax will be required to be read for several years.

Look over Química and environmental requirements

Fax paper may be handled frequently by receptionists, nurses, administrators and records personnel. Coating chemistry can thus be a key selection criteria for the institutional procurement.

Jin Bao Brother introduces the paper certifications currently available, como ISO, FSC, Libre de BPA, RoHS and SGS and TUV related paper certifications. The specific report always needs to be matched to a specific thermal paper grade given.

Don't use regular Papel de copia A4.

Sin embargo, with modern multifunction fax machines, regular A4 copy paper can be used, since the fax machine prints using laser or inkjet. In traditional thermal fax machines the imaging process is entirely different.

An ordinary copy paper can't make picture in a direct thermal fax machine. De forma similar, paper that requires heat to fax should not be put in a laser printer unless specifically stated.

Jin Bao Brother provides office A4 printer paper for normal office printing for laser, inkjet and plain paper fax equipment. Whether to use this paper or A4 thermal fax paper is entirely dependent on the fax machine used.

This feature is designed for use with legacy fax machines.

Legacy fax machines can keep going for many years when their paper specification is no longer readily available. Record of compatible media information should be retained prior to the replacement of staff, equipment labels or old procurement records.

It's a bad thing if there is too much stock. There is a risk of curling when stored for a long time or exposure to heat or humidity in storage. A practical reserve needs to find a balance between continuity of supply and reasonable rotation of stock.

Comprobación de selección final

Good thermal fax paper A4 should fit correctly in the physical paper compartment, lay the correct way up to the printhead and should have no excessive curl, dust or cutting issues.

The actual machine tests should be relied on when making purchase decisions, and not the A4 brand only. Anchura, Diámetro del rodillo, core design, Sensibilidad Térmica, smoothness of surface and image life and compliance should be established before the paper is sold at other sites.

Jin Bao Brother proporciona recubrimiento térmico, jumbo-roll converting and finished-paper processing. Application samples provide a good opportunity for organisations and distributors to test the compatibility with existing fax and thermal document equipment prior to regular supply.

Preguntas frecuentes

Q1. What's A4 thermal fax paper?

It is a heat-sensitive paper that is used in a direct thermal fax machine. It is usually sold as a roll, close to A4 size printing, instead of an office roll.

P2. What do you use for thermal fax paper?

No. The thermal printhead of the fax machine directly activates the coated surface to generate a printout without using ink, toner or a ribbon.

P3. Why a blank page is created from a fax machine?

The roll can have the uncoated side towards the printhead. Blank output can also be caused by incorrect paper type, lack of heat response or by a faulty printhead.

P4. Is there any possibility of using regular A4 paper instead of thermal fax paper?

Not in a direct thermal fax machine directly. The ordinary A4 paper can be used only in fax machines equipped with laser, ink jet or any other conventional printing systems.

P5. Where should printed thermal fax documents go?

Avoid exposure to oils, solventes, PVC materials, heat and sunlight. Important records should also be converted into more stable office paper (scanned or copied).
