At Honhai Technology, we do not believe you should pay exorbitant prices for “professional printing.” After over 18 years in the printer parts business, we have seen too many customers experience pain due to the high costs associated with OEM drum units. Today, we have the pleasure of introducing an industry-changing product: a high-performance refurbished Xerox drum unit.

“The Purple Standard”

One question asked frequently by our customers is, “How do you provide ‘original quality’ at a fraction of the OEM drum unit’s price?” The answer is simple: a four-step process. First, we take premium rebuilt drum frames and pair them with a brand-new purple Fuji drum core.

Why purple? Because in the realm of Xerox document reproduction, the special purple coating associated with Fuji drum technology represents the highest level of toner transfer and image stability. By using this exact technology in our Fuji drum core, we can provide your Xerox AltaLink/WorkCentre series with the quality of print output you have come to expect, minus the OEM price.

The unsung heroes of the corporate office and commercial printing world are today’s high-speed colour laser printers. They convert intricate digital files, legal documents and flashy marketing graphics into crisp hard copies every day. However, the precision and colour brilliance required to produce these documents are determined by a mass of carefully timed mechanical and electro-mechanical interactions. The fuser assembly, the system that drives the bonding of raw toner to the substrate of the paper at high temperatures and pressures, is at the heart of this process.In order to maintain excellence and efficient operation over time, businesses using the popular Color LaserJet Pro Series need to pay close attention to their core consumable items, in particular, their Fuser film sleeves (Part # M452dw M454DN M454dw PRO Mfp M377dw M477fdn M477fdw M479fdn).

Importance of Fuser Technology in Color Printing

Color laser printing requires significantly more from its fuser unit than traditional monochrome systems. A black-and-white printer only needs to fuse one layer of carbon black powder, while a color printer must intermix and “melt” 4 separate layers of toner (cyan – C, magenta – M, yellow – Y, and black – K). To accomplish this, color printers require precise thermal control, uniform pressure across the surface of the paper, and immediate transfer of thermal energy from the fuser to the toner layers. The fuser film used in these mid-speed color laser printers provides the direct thermal interface between the heating element and the four toner layers that have not yet fused. When proper thermal efficiency is not achieved by the film, heat will not be transmitted through to completion, causing incomplete melting and poor colour saturation.

If the fusing process does not meet the required standards, or if complete failure of the fusing results, users will see immediate results of this quality degradation. One example is poor toner adhesion, where printed text/images can be easily smeared, rubbed off, or flaked away with light rubbing friction. Additionally, many lower-end alternative sleeves are made with sub-standard quality, with surface defects or uneven coating. This causes an effect sometimes referred to as offset ghosting, where leftover toner is adhered to the sleeve and transferred to a page during the next cycle, resulting in waste of expensive paper and costly downtime to replace.

High-quality certified components are required to keep an uninterrupted flow of work; therefore, they are not simply an investment in maintenance, but are also an investment in protecting your work.

The fuser assembly contains several key components in addition to the sleeve.

While the film sleeve is the most visible piece of the fuser assembly, it relies on other parts to operate correctly and produce thousands of successful prints.

In order to operate successfully, many other parts in the fuser system must be in optimum condition. If one of the other components in the system is worn or defective, it will quickly and negatively impact the new sleeve and cause premature failure, creating a need for extensive troubleshooting.

  • The Pressure and Heat Core: The Pressure and Heat Core works directly with the Film Sleeve. The Pressure and Heat Core consists of the Lower Roller (also known as the Pressure Roller), which is located on the bottom of the fuser assembly, and the Upper Roller, which is on the top of the fuser assembly. Together, they form a “mechanical nip” where the paper passes through to allow for the fusing of the toner to the paper. Forces applied by the lower roller cause upward squeezing of liquefied toner deeply into the fibers within the paper. ISO specifications determine the elasticity and maximum load necessary for proper performance. If this or any other roller loses its elasticity and develops flat spots, or collects debris that affects the distribution of pressure, it will create uneven paper flow resulting in wrinkling, paper jams, or localized faint printing.

System cleanliness is essential for continued operation, and the printer housing and its interior cleanliness are critical to maintaining your printer in optimum condition. Internal roller and transfer system cleaning blades continually scour microscopic stray toner particles and paper dust from the rollers and transfer systems. It is essential to have effective cleaning systems in place, as contaminants will collect on delicate surface coatings, causing deep scratches on the film sleeve and affecting the clean transfer of text and graphics.

In addition to these mechanical components, there are two other systems critical to the life of the printer: the toner cartridge and the drum imaging systems. The OPC (Organic Photoconductor) drum functions as the light-sensitive canvas that the laser uses to create the latent electrostatic image. The OPC drum is contained in a substantial drum unit or drum frame that maintains precise alignment with the developer systems. If the drum surface is scratched or damaged, it can deposit incorrect quantities of toner onto the page, thereby overloading the fuser and causing background fogging, which, in turn, will prematurely clog the fuser film surface.

Understanding the HP Color LaserJet Pro Sweet Spot

The defined compatibility spectrum for the fuser film sleeve M452dw M454DN M454dw PRO Mfp M377dw M477fdn M477fdw M479fdn represents one of the largest market segments of corporate printing that exists today. These laser printers are widely used in small- to medium-sized businesses, medical offices, legal offices, and other corporate departments because they print at high speeds, offer extensive functionality, and are generally the most cost-effective to operate. Because these printers are built to produce print jobs at high volumes, their internal components see heavy use; therefore, service technicians often encounter them on service calls or during routine preventive maintenance.

The original fuser units are rated for a certain life cycle from the time they leave the factory, but when you consider real-world office conditions like different weights of paper, card stock, envelopes and aftermarket toner, the internal components can deteriorate much sooner than expected. Instead of paying for an entire OEM fuser assembly that costs a lot of money to replace, many intelligent service providers as well as businesses have begun rebuilding fusers by replacing only the sleeve and rollers that have worn out. By doing so, they drastically reduce the amount of money spent on maintenance and also keep electronic waste out of landfills, as long as the parts they are using to rebuild the units are produced to meet certain quality standards.

Honhai Technology, Ltd. recognizes that our customers’ businesses are reliant on the quality, reliability, and performance of the components we provide them. For that reason, Honhai Technology, Ltd. manufactures its fuser sleeves from high-quality imported materials, and it has established strict quality control procedures for the manufacturing of these sleeves. Our film utilizes a high-strength base material that has excellent physical strength, as well as extreme resistance to thermal elongation. Therefore, even with continuous, heavy printing, these sleeves will never warp, stretch, or crack.

Additionally, our sleeves have an advanced, proprietary non-stick outer coating. This ultra-smooth finish provides a non-stick surface for melted color toner to instantly release onto paper and not adhere to the sleeve; there is no ghosting, and the build-up of residue is significantly reduced. The inner sleeve lining is engineered to provide the perfect holding surface for fuser grease to create a low-friction interface between the sleeve and the ceramic heater. This low-friction design allows for ultra-smooth rotation to eliminate the jerking that contributes to registering paper irregularities and repeated paper wrinkling. Furthermore, Honhai’s compatible sleeves deliver brilliant colors and sharp text from the first page through the very last because of their design in conjunction with the thermal dynamics of the M452, M477, and M479 series.
