Unpacking and Component Identification
The Martin Yale Mark VII High-Speed Folder arrives packaged on a skid within a crate. Upon opening, you'll find several key components. The main unit is the most noticeable, but also expect separate boxes containing two fold tables, a motorized exit conveyor, and a friction feed table.
Before proceeding, carefully inspect all components for any damage incurred during shipping. Ensure all parts are present and in good condition. This initial check is crucial for a smooth setup process and prevents potential problems later.
Installing the Exit Conveyor and Fold Chart
Begin installation by attaching the exit conveyor. Connect the cord to the machine and secure it with the provided nut. Then slide the conveyor into place until it locks securely.
The simple fold chart, pre-installed on the exit tray extension, is attached to the machine using bolts on the exit tray. This chart provides essential guidance for different paper folding configurations.
Installing the Friction Feed Table and Fold Tables
Next, install the friction feed table on the opposite side of the main unit. Simply slide it into its designated slot and ensure it's firmly seated.
Install fold table number one (the longer table) on the upper side and fold table number two underneath the feed tray. Both tables snap into place easily.
Paper Handling and Adjustments
The Mark VII handles paper ranging from 16lb bond to 80lb cover, with sizes from 3 1/2" x 4 1/4" to 14" x 20". Adjustable paper guides accommodate this wide range.
The machine features variable speed controls for both the folding mechanism and the exit conveyor. Proper adjustment of the conveyor speed is vital to prevent stacking problems at higher folding speeds.
Jam Handle and Roller Gap Adjustment
A freewheeling jam handle prevents accidents during operation. To use it, pull out and turn the handle to engage the rollers and clear any jams.
Spring-loaded tongues on the machine's sides allow for precise roller gap adjustment based on paper weight. Use sample paper stock to set the gap for each fold.
Fold Chart and Stack Wheel Adjustments
The included fold chart simplifies setup for various folds and paper sizes, including standard and ISO sizes. Each setting includes specific fold plate positions and stack wheel positions.
The machine uses dual-adjustable stack wheels, offering flexibility to handle a wide range of paper sizes. These wheels can be adjusted in both height and position.
Setting up a Z-Fold and Fine Adjustments
The video demonstrates setting up the machine for an 8.5" x 11" Z-fold. Adjustments are made to the fold tables based on the chart and the paper's dimensions.
For non-square paper, independent fold stop adjustments allow for precise alignment. These micro-adjustments ensure clean folds even with imperfect paper cuts.
Throughput, Paper Feed, and Operation
The Mark VII boasts a throughput of 36,000 sheets per hour (based on half folds). Actual speed depends on the complexity of the fold and continuous loading by the operator.
The paper guides can hold a full ream of paper (500 sheets), though smaller quantities can be used. Adjust the sheet separator for optimal paper feeding based on environmental conditions.
Score/Perf Cartridge and Diverter
An optional score/perf cartridge allows for additional functionality. It is easily installed and removed. To use it, you'll need to remove the fold tables and mount the score/perf wheels.
To use the score/perf feature, reverse the fold tables. The fold table's diverter guides the paper directly through the scoring wheels without folding.
Mobile Stand and Conclusion
An optional mobile stand provides increased flexibility. This stand is specifically designed to fit the machine and includes caster wheels for easy mobility and also accommodates an air pump.
The Martin Yale Mark VII High-Speed Folder is a robust and versatile machine well-suited for high-volume folding needs. Its ease of setup, adjustable features, and optional accessories make it a valuable addition to any office or print shop.
