Mazzer Super Jolly Timer Stepless Doser Espresso Coffee Grinder

The Mazzer Super Jolly Timer is a great low-cost espresso coffee grinder for cafes and restaurants. The doser helps cut down wait times by pre-grinding your coffee. Also helps reduce waste by putting back any unused coffee grinds.

If you need a high-end grinder for your home, then the Mazzer Super Jolly Doser can definitely meet your needs. However, please note the very tall height will not fit under most cabinets.

Are you actually interested in a similar espresso coffee grinder that is electronic and doserless? Then check out the other version of the Mazzer Super Jolly!


  • Timer – Located on the side of the grinder. Turning the dial all the way will start the grinding process and will stop after 1 minute. To manually stop the grinding process, turn the dial back counterclockwise. The timer acts as a safety feature to prevent users from walking away and overflowing the grinder doser.

Grinding adjustment

  • Stepless – An infinite number of grind settings that allow you really fine-tune your grind. The adjustment dial is located underneath the hopper. The entire dial is numbered so you can remember your current grind setting easier. Turn clockwise for a coarser grind and counterclockwise for a finer grind.
  • Adjustment lever – This lever screws into the adjustment dial and helps you easily change your grind settings. There are 5 positions where you can install this lever. Once you find your correct grind setting, you can move the lever to another position that won’t stick out the sides.

Grinding burrs

  • Flat burrs – Very large size at 64 mm. The larger the size, the more of a grinding surface, resulting in faster production.
  • High rpm – A faster spinning rate at 1600 rpm. The higher the speed, the faster the production, which can increase efficiency and reduce wait times.
  • Easy access – Remove the bean hopper. Turn the grinding adjust to the coarser direction until the top assembly comes off. This will give you access to the burrs and the grinding chamber. The burrs themselves are held in with Allen key screws.

Bean hopper

  • Set screw – Secures the hopper to the grinder. Serves as a reminder for users from quickly removing the hopper if it is full of beans.
  • Finger guard – It prevents users from “accidentally” putting their fingers in the grinding burrs.
  • Stopper – A door near the bottom of the hopper slides inward to close the opening. This allows you to remove the hopper with beans inside so you can easily change the beans. There will be some beans already passed in the burrs which will have to be ground out first before removing the hopper.


  • Adjustable dosing – Allows you to change the amount of ground coffee dispensed into your portafilter.
  • Finger guard – Located in the dosing chamber.
  • Portafilter fork – Solid, chrome plated. Directs your portafilter right underneath the doser chute.
  • Built-in tamper – For those that want one. You can easily uninstall if you do not want to use.

ETL Certified

  • Effective July 17, 2006, all of our Mazzer Super Jolly Doser grinders have an ETL certification. ETL certification ensures that a manufacturer is utilizing quality components for product safety, and ongoing inspections and site visits by ETL ensure that manufacturers do not deviate from those standards of product safety. Ultimately, this ensures that internal components are the same (no cost-cutting) without the approval of ETL.

Espresso Grinder Warning

  • CLEANING WARNING: We recommend using grinder cleaning agents. We do not recommend any removal of the burrs or burr carrier for cleaning as re-assembly can cause damage.
  • ELECTRICAL WARNING: To avoid electrical damage to this espresso grinder which is not considered a manufacturer's defect, please acquire and install a single-outlet surge suppressor rated at 1080 joules or higher. The lack of the recommended surge suppressor, the espresso grinder can be damaged at the power switch, the capacitor, the motor, or the wiring.

  1. Changing grind settings: As with all coffee grinders, it is very important to only change grind settings when the unit is powered ‘on’ and the burrs are in motion. If you do not do this, the burrs will ‘gunk’ up and require cleaning by you every time this occurs. Changing the grind settings when the burrs are not in motion will render the grinder to only produce very coarse grinds or no grinds at all. If this result occurs, this will be considered operator error for lack of following directions, and not be classified as a defective grinder.
  2. Finding coffee grinds in a new grinder: We have confirmed that the manufacturer tests EVERY grinder with coffee beans before it leaves their facility, but they are not always able to get every trace of coffee out of the grinders after testing. As a result, you may find coffee beans or grinds inside your grinder, or there may be grinds in the packaging when you unwrap it.
  3. Static issues: There are static issues with all grinders, even the highest quality models. We firmly believe that the static comes from the coffee beans. If you are having static problems with your coffee grinder, trying using a different blend of beans.
  4. Replacing burrs: NEVER use a flat head screwdriver and hammer to wedge under the burrs for removal. This could badly damage your grinder.
  5. Electrical cord: Please note that the electrical cord is placed between the packaging (foam or cardboard) and the underside body of the grinder. During shipping, it is normal for a bend or insignificant blemish / slice to damage the cord.

      Sorry, the manufacturer does not offer these specifications. In general, the larger the burrs, the larger the chamber. Hence, the greater the burrs, generally the greater the chamber size, and generally the more retention of the grinds.

      One way to decrease retention is only place enough beans you will grind into the bean hopper and try to run the grinder so most of the grinds exit the grinding chamber. Then, sweep the chute between the grinder chamber and doser/doserless chute.

      If the grinder was purchased from 1st-line Equipment, please contact us via email with your full name, date of purchase, and order number so we can expedite to resolve inquiry. If purchased from another source, it is best to go back to the selling party/dealer as the selling party/dealer is responsible for any type of support on a new purchase.
