Decrease the print density setting. This will decrease the amount of background shading. Access this setting under “Printer properties (driver).”

Change the paper to a lighter basis weight. See “Printer paper specifications.”

Check the printer’s environment; very dry (low humidity) conditions can increase the amount of background shading.

Install a new HP toner cartridge. See “Changing the toner cartridge.”

Toner smear

If toner smears appear on the leading edge of the paper, the paper guides may be dirty. Wipe the paper guides with a dry, lint- free cloth. See “Printer components” or “Cleaning the printer.”

Check the paper type and quality.

Try installing a new HP toner cartridge. See “Changing the toner cartridge.”

Loose toner

Clean the inside of the printer. See “Cleaning the printer.”

Check the paper type and quality. See “Printer paper specifications.”

Try installing a new HP toner cartridge. See “Changing the toner cartridge.”

Vertical repetitive defects

The toner cartridge may be damaged. If a repetitive mark occurs at the same spot on the page, install a new HP toner cartridge. See “Changing the toner cartridge.”

Internal parts may have toner on them. See “Cleaning the printer.” If the defects occur on the back of the page, the problem will likely be corrected after a few more printed pages.

1100A specifications

The HP 1100 and 1100A are pivotal laser printers developed by Hewlett-Packard in the early 1990s, marking significant advancements in printing technology of their time. Since their introduction, these models have garnered a reputation for reliability and efficiency, making them a staple in many offices.

One of the standout features of the HP 1100 series is its fast printing speed. The printers can produce up to 12 pages per minute, which was an impressive feat at the time of their release. This speed significantly reduced waiting times, allowing users to handle large-volume printing jobs with ease. Furthermore, the printers support a variety of media types, including letterhead, envelopes, and labels, enhancing versatility in print applications.

The HP 1100 and 1100A utilize laser technology, which ensures sharp and high-quality prints. The printers have a native resolution of 600 x 600 dots per inch (DPI), enabling crisp text and detailed graphics. This high-resolution output made the models particularly favored for producing professional documents and presentations.

Another key characteristic is the generous memory capacity. The HP 1100 typically comes with 2 MB of standard RAM, which is expandable, allowing for improved performance in handling complex print jobs. Users can adjust the memory according to their requirements, resulting in better efficiency, particularly in environments that demand high-volume printing.

The HP 1100 series also showcases a straightforward and user-friendly operation. The built-in control panel simplifies the printing process, allowing users to manage jobs intuitively. Additionally, with the inclusion of parallel and later USB connectivity options, integration with various computer systems was seamless, ensuring compatibility with existing office infrastructure.

Energy efficiency is another aspect worth noting, as the printers are designed to consume minimal power when idle, aligning with the growing demand for eco-friendly solutions.

Overall, the HP 1100 and 1100A stand out for their robust construction, high-speed performance, exceptional print quality, and user-friendly features, making them a trusted choice for small to medium-sized businesses in need of dependable printing solutions. Their impact on the printing landscape during the 1990s continues to be felt today, as they paved the way for subsequent generations of laser printers.
