This disclosure relates generally to printer roller cleaning sheets and a method of use thereof, and more particularly to printer roller cleaning sheets adapted for use in different ways to clean thermal printer rollers.
One of the most common causes of paper feed problems in a printer (e.g., a thermal printer) is a dirty roller. The roller is responsible for pulling the paper through the printer, and when not clean, the roller may not be able to grip the paper correctly, causing the paper to slip, bunch up, or feed at an angle, which can lead to paper jams. Silicon cleaning pens are often used to clean a print roller in a thermal printer, but this must be done on a regular basis (e.g., monthly). For printers mounted in remote locations, such as within a self-service terminal, this necessitates regular service calls for cleaning. When the printer is remotely installed, such as in a self-service terminal, it becomes even more important to regularly clean the printer roller, because a paper jam can cause the self-service terminal to go out of service until an expedited (and potentially costly) service call is arranged to clear the paper jam. Thermal printers of the type used in self-service terminals can be more likely to experience paper jams caused by dirty rollers because the paper is typically fed from a roll of paper and cut with an internal cutter to generate a transaction receipt, for example. The process of cutting the paper can generate internal dust and other paper residue that can accumulate on the printer roller, which over time can reduce the effectiveness of the printer roller.
Accordingly, there is a need for an improved way to clean the roller of the printer, particularly a remotely-located printer, in order to preclude paper jams that could require costly service calls to resolve.
The following detailed description, given by way of example and not intended to limit the present disclosure solely thereto, will best be understood in conjunction with the accompanying drawings in which:
In the present disclosure, like reference numbers refer to like elements throughout the drawings, which illustrate various exemplary embodiments of the present disclosure.

Polyester cellulose wipes, also known as polyester/cellulose nonwoven wipes, are a type of cleaning wipe or cloth that is commonly used in various industries, including healthcare, electronics, and manufacturing. These wipes can be provided in sheet form and are composed of a blend of polyester fibers and cellulose fibers. Polyester is a synthetic fiber known for its durability, strength, and resistance to chemicals. It provides the wipe with enhanced abrasion resistance, making it suitable for more rigorous cleaning tasks. Polyester fibers also offer good absorbency, allowing the wipe to soak up liquids effectively. Cellulose, on the other hand, is a natural fiber derived from plant sources, such as wood pulp. It provides the wipe with softness and improved absorbency. Cellulose fibers can hold and retain liquids, making them effective for wiping surfaces and absorbing spills. The combination of polyester and cellulose fibers in these wipes results in a material that combines the benefits of both. Polyester cellulose wipes are typically low-linting, meaning they shed minimal fibers during use, which is especially important in applications where cleanliness and particulate control are crucial, such as in cleanrooms or electronics manufacturing. These wipes are available in various sizes and forms, such as rolls, sheets, or pre-cut pieces, to accommodate different cleaning needs.
The present inventors have found that a sheet of polyester cellulose material is extremely effective at cleaning printer rollers and thereby preventing the accumulation of dust and paper debris on printer rollers in order to prevent jams and other paper feed problems. Because polyester cellulose material is low linting, there is almost no shedding of fibers or other debris. This makes polyester cellulose material an optimal material for use in cleaning a printer roller. By passing a sheet of polyester cellulose material through the printer paper path, any dust and paper debris that may have accumulated on the printer roller will adhere to the fibrous surface of the ## #polyester cellulose sheet and pass out of the printer. This material has been found to be very effective for cleaning a printer roller since its lint-free nature ensures that all of the dust and debris accumulated on the printer roller can be removed with no remnants whatsoever from the material. Because polyester cellulose material can easily be formed into sheets or rolls like paper and with the same size and form, it is an ideal solution for cleaning printer rollers.

Thermal printers typically use rolls of paper, as discussed herein. Many other types of printers use rollers as part of a feeding process for sheets of paper from a ream of paper. All of these printers can be subject to similar print jams due to dirty rollers. Referring now to

The method of this disclosure is very quick, inexpensive, and effective in keeping printer rollers clean and clear of dust and paper debris. When used regularly with thermal printers at self-service terminals, costly shutdowns and service calls are avoided.
The printer roller cleaning sheets may be provided as a roll of polyester cellulose material for use in cleaning one or more printer rollers in a printer. Such a roll may be a nonwoven fabric having a blend of polyester fibers and cellulose fibers. The nonwoven fabric may be in the form of a continuous sheet wound around a core. The nonwoven fabric may be designed and configured to effectively remove debris from printer rollers. The roll of polyester cellulose material may be configured to replace a roll of paper in the printer in order to perform a cleaning function of the one or more printer rollers.
In one alternative, the printer roller cleaning sheets may be provided as a combined roll of printer paper and polyester cellulose material for use in cleaning one or more printer rollers in a printer. The combined roll has a continuous sheet of printer paper wound around a core. The combined roll also has a nonwoven fabric having a blend of polyester fibers and cellulose fibers. The nonwoven fabric may be in the form of a continuous sheet coupled (bound) to and wound over the continuous sheet of printer paper. The nonwoven fabric may be designed and configured to effectively remove debris from printer rollers. The combined roll of polyester cellulose material may be configured to replace a roll of paper in the printer in order to perform a cleaning function of the one or more printer rollers upon an initial installation of the combined roll of polyester cellulose material into the printer.
In another alternative, the printer roller cleaning sheets may be provided as a polyester cellulose material for use in cleaning one or more printer rollers in a printer. The printer roller cleaning sheets may have a nonwoven fabric comprising a blend of polyester fibers and cellulose fibers. The nonwoven fabric may be in the form of separate sheets adapted to fit into a paper compartment of a printer. The nonwoven fabric may be designed and configured to effectively remove debris from printer rollers. The polyester cellulose material may be for cleaning the one or more printer rollers upon installation into the printer.
Although the present disclosure has been particularly shown and described with reference to the preferred embodiments and various aspects thereof, it will be appreciated by those of ordinary skill in the art that various changes and modifications may be made without departing from the spirit and scope of the disclosure. It is intended that the appended claims be interpreted as including the embodiments described herein, the alternatives mentioned above, and all equivalents thereto.
